Railroad tracks first reached the borough in 1854. A sawmill
36-471: A town in most jurisdictions, usually smaller than a city , but with a similar population density in its residential areas. Sometimes thought of as "junior cities", boroughs generally have fewer powers and responsibilities than full-fledged cities. All municipalities in Pennsylvania are classified as either cities , boroughs, or townships . The only exception is the town of Bloomsburg , recognized by
54-569: A fast pace. Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Very densely populated cities are mostly in Asia (particularly Southeast Asia ); Africa's Lagos , Kinshasa , and Cairo ; South America's Bogotá , Lima , and São Paulo ; and Mexico City and Saint Petersburg also fall into this category. City population and especially area are, however, heavily dependent on
72-472: A female householder with no husband present, and 38.8% were non-families. 33.2% of all households were made up of individuals, and 15.9% had someone living alone who was 65 years of age or older. The average household size was 2.21 and the average family size was 2.81. In the borough the population was spread out, with 21.1% under the age of 18, 7.2% from 18 to 24, 27.3% from 25 to 44, 23.1% from 45 to 64, and 21.3% who were 65 years of age or older. The median age
90-538: A high urbanization level, with an economically specialized city population drawing also on rural resources outside the area, illustrating the difference between high population density and overpopulation . Deserts have very limited potential for growing crops as there is not enough rain to support them. Thus, their population density is generally low. However, some cities in the Middle East, such as Dubai , have been increasing in population and infrastructure growth at
108-478: Is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are: Population density is the number of people per unit of area, usually transcribed as "per square kilometer" or square mile, and which may include or exclude, for example, areas of water or glaciers. Commonly this is calculated for a county , city , country , another territory or
126-519: Is mostly residential, with some forest and industrial areas. The West Branch Susquehanna River borders the western part of Watsontown. The borough is served by Pennsylvania Route 44 and Pennsylvania Route 405 . As of the census of 2000, there were 2,254 people, 967 households, and 591 families residing in the borough. The population density was 3,161.9 inhabitants per square mile (1,220.8/km). There were 1,017 housing units at an average density of 1,426.0 per square mile (550.6/km). The racial makeup of
144-518: Is taken into account, then human population density is 53/km (140/sq mi). This includes all continental and island land area, including Antarctica . However, if Antarctica is excluded, then population density rises to over 58 per square kilometre (150/sq mi). The European Commission's Joint Research Centre (JRC) has developed a suite of (open and free) data and tools named the Global Human Settlement Layer (GHSL) to improve
162-494: The entire world . The world's population is around 8,000,000,000 and the Earth 's total area (including land and water) is 510,000,000 km (200,000,000 sq mi). Therefore, the worldwide human population density is approximately 8,000,000,000 ÷ 510,000,000 = 16/km (41/sq mi). However, if only the Earth's land area of 150,000,000 km (58,000,000 sq mi)

#1732844265610216-547: The definition of "urban area" used: densities are almost invariably higher for the center only than when suburban settlements and intervening rural areas are included, as in the agglomeration or metropolitan area (the latter sometimes including neighboring cities). In comparison, based on a world population of 8 billion, the world's inhabitants, if conceptualized as a loose crowd occupying just under 1 m (10 sq ft) per person (cf. Jacobs Method ), would occupy an area of 8,000 square kilometres (3,100 sq mi)
234-545: The science for policy support to the European Commission Directorate Generals and Services and as support to the United Nations system. Several of the most densely populated territories in the world are city-states , microstates and urban dependencies . In fact, 95% of the world's population is concentrated on just 10% of the world's land. These territories have a relatively small area and
252-574: The state government as the only incorporated town in Pennsylvania. Boroughs tend to have more developed business districts and concentrations of public and commercial office buildings, including courthouses. Boroughs are larger, less spacious, and more developed than the relatively rural townships, which often have the greater territory and even surround boroughs of a related or even the same name. There are 956 boroughs and 56 cities in Pennsylvania. Many home rule municipalities remain classified as boroughs or townships for certain purposes, even if
270-539: The state's borough and township codes no longer apply to them. Population density Population density (in agriculture : standing stock or plant density ) is a measurement of population per unit land area. It is mostly applied to humans , but sometimes to other living organisms too. It is a key geographical term. Population density is population divided by total land area , sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This

According to the United States Census Bureau , the borough has a total area of 0.9 square miles (2.3 km), of which 0.7 square miles (1.8 km) is land and 0.2 square miles (0.52 km) (24.47%) is water. Watsontown's terrain is almost entirely flat except for a hill in the eastern part of the borough. The borough's land
