J-curve: This is when the projection population show exponential growth; sometimes shape as a j-curve. This is important because if the population grows exponential our resource use will go up exponential and so will our use as well as a greater demand for food and more.

Define population center. Average location of everyone in the country/”center of population gravity”

Population Geography relates spatial variations in the distribution, composition, migration, and growth of populations to the terrain. Population geography involves demography in a geographical perspective. It focuses on the characteristics of population distributions that change in a spatial context.

A census counts the population of a nation, state, or other geographic region. It records information about the population’s characteristics, such as age, sex, and occupation.

Collection of data from a whole population rather than just a sample. Example: doing a survey of travel time by … asking everyone at school is a census (of the school).

An example of population distribution is the fact that China’s natural physical conditions resulted in uneven population distribution. There is a huge contrast in the number of people living in eastern China compared to the distribution in the western part of the country.

Individuals of a population can be distributed in one of three basic patterns: uniform, random, or clumped.

Population density is the average number of individuals in a population per unit of area or volume. For example, a population of 100 insects that live in an area of 100 square meters has a density of 1 insect per square meter.

26,150.3 residents per square kilometer

The formula for population density is Dp= N/A, where Dp is the population density, N is the total population, and A is the land area covered by the population. For human populations, A is typically expressed as square miles or square kilometers. For example, you might use square meters, square feet, or acres.

Arithmetic population density can be misleading because it does not show the uneven distribution of population in a country. Physiologic population density can more accurately show the population pressure of a country as it is defined as the number of people per agriculturally productive (arable) land.

Population density is the number of people per unit of area, usually quoted per square kilometre or square mile, and which may include or exclude for example areas of water or glaciers. Commonly this may be calculated for a county, city, country, another territory or the entire world.

Population density is the number of individuals per unit geographic area, for example, number per square meter, per hectare, or per square kilometer.
