In demography , demographic transition is a phenomenon and theory which refers to the historical shift from high birth rates and high death rates to low birth rates and low death rates, as societies attain more technology, education (especially of women ) and economic development . The demographic transition has occurred in most of the world over the past two centuries, bringing the unprecedented population growth of the post-Malthusian period , then reducing birth rates and population growth significantly in all regions of the world. The demographic transition strengthens economic growth process by three changes: (i) reduced dilution of capital and land stock, (ii) increased investment in human capital, and (iii) increased size of the labor force relative to the total population and changed age population distribution. Although this shift has occurred in many industrialized countries , the theory and model are frequently imprecise when applied to individual countries due to specific social, political and economic factors affecting particular populations.
101-572: Crenshaw , or the Crenshaw District , is a neighborhood in South Los Angeles , California. In the post– World War II era, a Japanese American community was established in Crenshaw. African Americans started migrating to the district in the mid 1960s, and by the early 1970s were the majority. The Crenshaw Boulevard commercial corridor has had many different cultural backgrounds throughout
202-526: A Stage Five. Some countries have sub-replacement fertility (that is, below 2.1–2.2 children per woman). Replacement fertility is generally slightly higher than 2 (the level which replaces the two parents, achieving equilibrium) both because boys are born more often than girls (about 1.05–1.1 to 1), and to compensate for deaths prior to full reproduction. Many European and East Asian countries now have higher death rates than birth rates. Population aging and population decline may eventually occur, assuming that
303-500: A certain demographic dynamism, with a growth rate of 2.4% between 2000 and 2005, above the European average. More than two-thirds of that growth can be ascribed to a natural increase resulting from high fertility and birth rates. In contrast, France is one of the developed nations whose migratory balance is rather weak, which is an original feature at the European level. Several interrelated reasons account for such singularities, in particular
404-570: A demographic transition with high death rate and low fertility rate from 1959 to 1961 due to the great famine. However, as a result of the economic improvement, the birth rate increased and mortality rate declined in China before the early 1970s. In the 1970s, China's birth rate fell at an unprecedented rate, which had not been experienced by any other population in a comparable time span. The birth rate fell from 6.6 births per women before 1970 to 2.2 births per women in 1980.The rapid fertility decline in China

Countries that have experienced a fertility decline of less than 25% include: Sudan , Niger , Afghanistan . This occurs where birth and death rates are both low, leading to a total population stability. Death rates are low for a number of reasons, primarily lower rates of diseases and higher production of food. The birth rate
606-452: A fertility transition beginning in post-1965. As of 2013, India is in the later half of the third stage of the demographic transition, with a population of 1.23 billion. It is nearly 40 years behind in the demographic transition process compared to EU countries , Japan , etc. The present demographic transition stage of India along with its higher population base will yield a rich demographic dividend in future decades.

Many countries such as China , Brazil and Thailand have passed through the Demographic Transition Model (DTM) very quickly due to fast social and economic change. Some countries, particularly African countries, appear to be stalled in the second stage due to stagnant development and
909-495: A negative demographic force. Infertility and infant mortality, which were probably more significant influences on overall population levels than the adult mortality rate, increased from 1820 due to disease, malnutrition, and stress, all of which stemmed from state forced labor policies. Available estimates indicate little if any population growth for Madagascar between 1820 and 1895. The demographic "crisis" in Africa, ascribed by critics of
1010-490: A negative migratory flow – two-thirds of rural communities have shown some since 2000. The spatial demographic expansion of large cities amplifies the process of peri-urbanization yet is also accompanied by movement of selective residential flow, social selection, and sociospatial segregation based on income. McNicoll (2006) examines the common features behind the striking changes in health and fertility in East and Southeast Asia in
1111-464: A panel data set to explore how industrial revolution, demographic transition, and human capital accumulation interacted in Korea from 1916 to 1938. Income growth and public investment in health caused mortality to fall, which suppressed fertility and promoted education. Industrialization, skill premium, and closing gender wage gap further induced parents to opt for child quality. Expanding demand for education

Between 1750 and 1975 England experienced the transition from high to low levels of both mortality and fertility. A major factor was the sharp decline in the death rate due to infectious diseases, which has fallen from about 11 per 1,000 to less than 1 per 1,000. By contrast,

Under racially restrictive covenants, blacks were allowed to own property only within the "Slauson Box" (the area bounded by Main, Slauson, Alameda, and Washington) and in Watts, as well as in small enclaves elsewhere in the city. The working- and middle-class blacks who poured into Los Angeles during the Great Depression and in search of jobs during World War II found themselves penned into what

Since then, a number of protests focused on events in Ferguson have taken place in South Los Angeles. After the 2008 economic recession, housing prices in South Los Angeles recovered significantly, and by 2018, many had come to see South Los Angeles as
1717-499: A sharp chronological divide between the precolonial and colonial eras, arguing that whereas "natural" demographic influences were of greater importance in the former period, human factors predominated thereafter. Campbell argues that in 19th-century Madagascar the human factor, in the form of the Merina state , was the predominant demographic influence. However, the impact of the state was felt through natural forces, and it varied over time. In
1818-557: A substantial portion of which traditionally had been performed by children in farm families. A simplification of the DTM theory proposes an initial decline in mortality followed by a later drop in fertility. The changing demographics of the U.S. in the last two centuries did not parallel this model. Beginning around 1800, there was a sharp fertility decline; at this time, an average woman usually produced seven births per lifetime, but by 1900 this number had dropped to nearly four. A mortality decline

It is "defined on Los Angeles city maps as a 16-square-mile (41 km ) rectangle with two prongs at the south end.” In 2003, the Los Angeles City Council renamed this area "South Los Angeles". The name South Los Angeles can also refer to a larger 51-square-mile (130 km ) region that includes areas within
2121-412: Is exerting evolutionary pressure for higher fertility, and that eventually due to individual natural selection or cultural selection, birth rates may rise again. Part of the "cultural selection" hypothesis is that the variance in birth rate between cultures is significant; for example, some religious cultures have a higher birth rate that is not accounted for by differences in income.

The DTM (Demographic Transition model) is only a suggestion about the future population levels of a country, not a prediction. Countries that were at this stage ( total fertility rate between 2.0 and 2.5) in 2015 include: Antigua and Barbuda, Argentina, Bahrain, Bangladesh, Bhutan, Cabo Verde, El Salvador, Faroe Islands, Grenada, Guam, India, Indonesia, Kosovo, Libya, Malaysia, Maldives, Mexico, Myanmar, Nepal, New Caledonia, Nicaragua, Palau, Peru, Seychelles, Sri Lanka, Suriname, Tunisia, Turkey and Venezuela.

This may be the result of a departure from the environment of evolutionary adaptedness . Most models posit that the birth rate will stabilize at a low level indefinitely. Some dissenting scholars note that the modern environment

Eighty-two-year-old Jimmy Jike was quoted in the Los Angeles Times in 1993, stating that it was mainly because the residents' children, after attending universities, moved away. By 1980, there were 4,000 Japanese ethnic residents, half of

In the eastern side of South Los Angeles (which the city calls the "Southeastern CPA") roughly east of the Harbor Freeway, the area grew southward in the late 1800s along the ever-longer streetcar routes. Areas north of Slauson Boulevard were mostly built out by the late 1910s, while south of Slauson land

In the 2000s Oded Galor researched the "various mechanisms that have been proposed as possible triggers for the demographic transition, assessing their empirical validity, and their potential role in the transition from stagnation to growth." In 2011, the unified growth theory was completed, the demographic transition becomes an important part in unified growth theory. By 2009,

DTM assumes that population changes are induced by industrial changes and increased wealth, without taking into account the role of social change in determining birth rates, e.g., the education of women. In recent decades more work has been done on developing the social mechanisms behind it. DTM assumes that the birth rate is independent of

Freeway routes tended to reinforce traditional segregation lines. Beginning in the 1970s, the rapid decline of the area's manufacturing base resulted in a loss of the jobs that had allowed skilled union workers to enjoy a middle-class lifestyle. Downtown Los Angeles' service sector, which had long been dominated by unionized African Americans earning relatively fair wages, replaced most black workers with newly arrived Mexican and Central American immigrants.

Today, the U.S. is recognized as having both low fertility and mortality rates. Specifically, birth rates stand at 14 per 1000 per year and death rates at 8 per 1000 per year. Because the DTM is only a model, it cannot necessarily predict
4949-404: The death rate falls or improves, this may include lower infant mortality rate and increased child survival. Over time, as individuals with increased survival rates age, there may also be an increase in the number of older children, teenagers, and young adults. This implies that there is an increase in the fertile population proportion which, with constant fertility rates , may lead to an increase in

Scientific discoveries and medical breakthroughs did not, in general, contribute importantly to the early major decline in infectious disease mortality. In the 1980s and early 1990s, the Irish demographic status converged to the European norm. Mortality rose above the European Community average, and in 1991 Irish fertility fell to replacement level. The peculiarities of Ireland's past demography and its recent rapid changes challenge established theory. The recent changes have mirrored inward changes in Irish society, with respect to family planning, women in

Notably, some historic populations have taken many years to replace lives after events such as the Black Death . Some have claimed that DTM does not explain the early fertility declines in much of Asia in the second half of the 20th century or

This change in population occurred in north-western Europe during the nineteenth century due to the Industrial Revolution . During

In pre-industrial society, death rates and birth rates were both high, and fluctuated rapidly according to natural events, such as drought and disease, to produce a relatively constant and young population. Family planning and contraception were virtually nonexistent; therefore, birth rates were essentially only limited by
5757-560: The existence of a negative correlation between fertility and industrial development had become one of the most widely accepted findings in social science. The Jews of Bohemia and Moravia were among the first populations to experience a demographic transition, in the 18th century, prior to changes in mortality or fertility in other European Jews or in Christians living in the Czech lands . John Caldwell (demographer) explained fertility rates in
5858-636: The existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development. Scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. Scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income, lower mortality , old-age security, and rise of demand for human capital are involved. Human capital gradually increased in

When the death rate declines during the second stage of the transition, the result is primarily an increase in the younger population.

Both supporters and critics of the theory hold to an intrinsic opposition between human and "natural" factors, such as climate, famine, and disease, influencing demography. They also suppose

Most particularly, of course, the DTM makes no comment on change in population due to migration. It is not necessarily applicable at very high levels of development.

6666-412: The late 18th and early 19th centuries Merina state policies stimulated agricultural production, which helped to create a larger and healthier population and laid the foundation for Merina military and economic expansion within Madagascar. From 1820, the cost of such expansionism led the state to increase its exploitation of forced labor at the expense of agricultural production and thus transformed it into

With low mortality but stage 1 birth rates, the United States necessarily experienced exponential population growth (from less than 4 million people in 1790, to 23 million in 1850, to 76 million in 1900). The only area where this pattern did not hold was the American South. High prevalence of deadly endemic diseases such as malaria kept mortality as high as 45–50 per 1000 residents per year in 18th century North Carolina. In New Orleans , mortality remained so high (mainly due to yellow fever ) that

By 1970 Russia was firmly in stage four, with crude birth rates and crude death rates on the order of 15/1000 and 9/1000 respectively. Bizarrely, however, the birth rate entered a state of constant flux, repeatedly surpassing

France's demographic profile is similar to its European neighbors and to developed countries in general, yet it seems to be staving off the population decline of Western countries.

Greenwood and Seshadri (2002) show that from 1800 to 1940 there was a demographic shift from a mostly rural US population with high fertility, with an average of seven children born per white woman, to a minority (43%) rural population with low fertility, with an average of two births per white woman. This shift resulted from technological progress. A sixfold increase in real wages made children more expensive in terms of forgone opportunities to work and increases in agricultural productivity reduced rural demand for labor,

However, unless factors such as those listed above are allowed to work, a society's birth rates may not drop to a low level in due time, which means that
7474-441: The population. In Stage One, the majority of deaths are concentrated in the first 5–10 years of life. Therefore, more than anything else, the decline in death rates in Stage Two entails the increasing survival of children and a growing population. Hence, the age structure of the population becomes increasingly youthful and start to have big families and more of these children enter the reproductive cycle of their lives while maintaining
7575-561: The previous size. By 1990 there were 2,500 Japanese-Americans, mostly older residents. By 1993, the community was diminishing in size, with older Japanese Americans staying but with younger ones moving away. That year, Dai-Ichi Gakuen had 15 students. In the 90s there began a shift to a new generation of Japanese Americans moving back into the neighborhood. Public schools are operated by the Los Angeles Unified School District (LAUSD). The district's charter schools in
7676-587: The region. According to scholars, "Between 1970 and 1990 the South LA area went from 80% African American and 9% Latino to 50.3% African American and 44% Latino." Many African Americans from South Los Angeles have moved to Palmdale and Lancaster in the Antelope Valley . South Los Angeles has received immigrants from Mexico and Central America . According to the city's "2014 South Los Angeles Community Plan Area Demographic Profile", South Los Angeles had
7777-584: The rise of street gangs in South Central, such as the Crips and the Bloods . The gangs became even more powerful with money coming in from drugs, especially the crack cocaine trade that was dominated by gangs in the 1980s. Paul Feldman of the Los Angeles Times wrote in 1989: Leaders of the black community regret the branding of a large, predominantly black sector of the city as South-Central, saying it amounts to
7878-407: The second half of the twentieth century less-developed countries entered Stage Two, creating the worldwide rapid growth of number of living people that has demographers concerned today. In this stage of DT, countries are vulnerable to become failed states in the absence of progressive governments. Another characteristic of Stage Two of the demographic transition is a change in the age structure of
7979-604: The second stage of the industrial revolution, which coincided with the demographic transition. The increasing role of human capital in the production process led to the investment of human capital in children by families, which may be the beginning of the demographic transition. The theory is based on an interpretation of demographic history developed in 1930 by the American demographer Warren Thompson (1887–1973). Adolphe Landry of France made similar observations on demographic patterns and population growth potential around 1934. In
8080-548: The society cannot proceed to stage three and is locked in what is called a demographic trap . Countries that have witnessed a fertility decline of over 50% from their pre-transition levels include: Costa Rica , El Salvador , Panama , Jamaica , Mexico , Colombia , Ecuador , Guyana , Philippines , Indonesia , Malaysia , Sri Lanka , Turkey , Azerbaijan , Turkmenistan , Uzbekistan , Tunisia , Algeria , Morocco , Lebanon , South Africa , India , Saudi Arabia , and many Pacific islands . Countries that have experienced
8181-453: The southwest and along the Atlantic coast, plus dynamism in metropolitan areas. Shifts in population between regions account for most of the differences in growth. The varying demographic evolution regions can be analyzed though the filter of several parameters, including residential facilities, economic growth, and urban dynamism, which yield several distinct regional profiles. The distribution of
8282-444: The third world are not dependent on the spread of industrialization or even on economic development and also illustrates fertility decline is more likely to precede industrialization and to help bring it about than to follow it. The transition involves four stages, or possibly five. As with all models, this is an idealized picture of population change in these countries. The model is a generalization that applies to these countries as
8383-547: The time span in which it is experienced. Stage Three moves the population towards stability through a decline in the birth rate. Several fertility factors contribute to this eventual decline, and are generally similar to those associated with sub-replacement fertility , although some are speculative: The resulting changes in the age structure of the population include a decline in the youth dependency ratio and eventually population aging . The population structure becomes less triangular and more like an elongated balloon. During
8484-506: The time. After leading the nation in homicides again in 2002, the City Council of Los Angeles voted to change the name South Central Los Angeles to South Los Angeles on all city documents in 2003, a move supporters said would "help erase a stigma that has dogged the southern part of the city." On August 11, 2014, just two days after the shooting of Michael Brown in Ferguson, Missouri ,
8585-563: The transition in the 18th century, simultaneously with the rest of Europe, though the effect of transition remained limited to a modest decline in death rates and steady population growth. The population of Russia nearly quadrupled during the 19th century, from 30 million to 133 million, and continued to grow until the First World War and the turmoil that followed. Russia then quickly transitioned through stage three. Though fertility rates rebounded initially and almost reached 7 children/woman in
8686-443: The trends in fertility." In 2004 a United Nations office published its guesses for global population in the year 2300; estimates ranged from a "low estimate" of 2.3 billion (tending to −0.32% per year) to a "high estimate" of 36.4 billion (tending to +0.54% per year), which were contrasted with a deliberately "unrealistic" illustrative "constant fertility" scenario of 134 trillion (obtained if 1995–2000 fertility rates stay constant into
8787-442: The twentieth century, the falls in death rates in developing countries tended to be substantially faster. Countries in this stage include Yemen , Afghanistan , and Iraq and much of Sub-Saharan Africa (but this does not include South Africa , Botswana , Eswatini , Lesotho , Namibia , Gabon and Ghana , which have begun to move into stage 3). The decline in the death rate is due initially to two factors: A consequence of
8888-430: The videotaped police brutality of Rodney King . By the early 2010s, the crime rate of South Los Angeles had declined significantly. Redevelopment, improved police patrol, community-based peace programs, gang intervention work, and youth development organizations lowered the murder and crime rates to levels that had not been seen since the 1940s and 1950s. Nevertheless, South Los Angeles was still known for its gangs at
8989-462: The western United States. In 2006, the population of Crenshaw was around 27,600. Currently, there is a huge demographic shift increase in which many middle and lower-class blacks and Latinos are migrating to cities in the Inland Empire as well as cities in the Antelope Valley sections of Southern California as a form of gentrification . The gentrification process continues into 2010's as
9090-548: The wild. This is the earlier stage of demographic transition in the world and also characterized by primary activities such as small fishing activities, farming practices, pastoralism and petty businesses. This stage leads to a fall in death rates and an increase in population. The changes leading to this stage in Europe were initiated in the Agricultural Revolution of the eighteenth century and were initially quite slow. In
9191-462: The work force, the sharply declining power of the Catholic Church, and the emigration factor. France displays real divergences from the standard model of Western demographic evolution. The uniqueness of the French case arises from its specific demographic history, its historic cultural values, and its internal regional dynamics. France's demographic transition was unusual in that the mortality and
9292-407: The working ages. This stage of the transition is often referred to as the golden age, and is typically when populations see the greatest advancements in living standards and economic development. However, further declines in both mortality and fertility will eventually result in an aging population, and a rise in the aged dependency ratio . An increase of the aged dependency ratio often indicates that
9393-499: The years, but it is still "the heart of African American commerce in Los Angeles". Crenshaw had suffered significant damage from both the 1992 Los Angeles riots and the 1994 Northridge earthquake but was able to rebound in the late 2000s with the help of redevelopment and gentrification . According to Google Maps, the Crenshaw neighborhood is centered on Crenshaw Boulevard and Buckingham Road. The neighborhood of Baldwin Hills
9494-466: Was accommodated by an active public school building program. The interwar agricultural depression aggravated traditional income inequality, raising fertility and impeding the spread of mass schooling. Landlordism collapsed in the wake of de-colonization, and the consequent reduction in inequality accelerated human and physical capital accumulation, hence leading to growth in South Korea. China experienced
9595-687: Was all that prevented a widow from falling into destitution. While death rates remained high there was no question as to the need for children, even if the means to prevent them had existed. During this stage, the society evolves in accordance with Malthusian paradigm, with population essentially determined by the food supply. Any fluctuations in food supply (either positive, for example, due to technology improvements, or negative, due to droughts and pest invasions) tend to translate directly into population fluctuations. Famines resulting in significant mortality are frequent. Overall, population dynamics during stage one are comparable to those of animals living in
9696-463: Was becoming a severely overcrowded neighborhood. During the war, blacks faced such dire housing shortages that the Housing Authority of the City of Los Angeles built the virtually all-black and Latino Pueblo Del Rio project, designed by Richard Neutra . During this time, African Americans remained a minority alongside whites, Asians, and Hispanics; but by the 1930s those groups moved out of
9797-420: Was caused by government policy: in particular the "later, longer, fewer" policy of the early 1970s and in the late 1970s the one-child policy was also enacted which highly influence China demographic transition. As the demographic dividend gradually disappeared, the government abandoned the one-child policy in 2011 and fully lifted the two-child policy from 2015.The two-child policy has had some positive effects on
9898-468: Was confined to the Central Avenue corridor"; the area of modest bungalows and low-rise commercial buildings along Central Avenue emerged as the heart of the black community in southern California. Originally, the city's black community was concentrated around what is now Little Tokyo , but began moving south after 1900. It had one of the first jazz scenes in the western U.S., with trombonist Kid Ory
9999-414: Was mostly undeveloped, much used by Chinese and Japanese Americans growing produce. In 1903, the farmers were bought out and Ascot Park racetrack was built, which turned into a "den of gambling and drinking". In the late 1910s the park was razed and freed up land for quick build-up of residential and industrial buildings in the 1920s. "By 1940, approximately 70 percent of the black population of Los Angeles
10100-402: Was not observed in the U.S. until almost 1900—a hundred years after the drop in fertility. However, this late decline occurred from a very low initial level. During the 17th and 18th centuries, crude death rates in much of colonial North America ranged from 15 to 25 deaths per 1000 residents per year (levels of up to 40 per 1000 being typical during stages one and two). Life expectancy at birth
10201-504: Was on the order of 40 and, in some places, reached 50, and a resident of 18th century Philadelphia who reached age 20 could have expected, on average, additional 40 years of life. This phenomenon is explained by the pattern of colonization of the United States. Sparsely populated interior of the country allowed ample room to accommodate all the "excess" people, counteracting mechanisms (spread of communicable diseases due to overcrowding, low real wages and insufficient calories per capita due to
