Subtracting a past population value from the present population value, and dividing this result by the past population value, yields the population-growth rate. Multiplying the population-growth rate by 100 yields the growth percentage.
Population density tells you how crowded a certain area is, on average. To calculate, you need measurements of area, the population count and a calculator.
The United States Census Bureau provides a calculation of current residents through a population clock published on its website. The population clock includes an estimate of all individuals usually residing in the 50 states and the District of Columbia, regardless of citizenship status. However, the
Calculate population growth rate by dividing the change in population by the initial population, multiplying it by 100, and then dividing it by the number of years over which that change took place. The number is expressed as a percentage.
Countries throughout the world use varying methods to control the population, including reducing infant mortality, changing women's status, contraception, sterilization, abstinence, abortion and legislation. The cultural and religious beliefs of a community may influence the methods they use.
The basic equation for calculating population growth multiplies the population size by the per capita growth rate, which is calculated by subtracting the per capita death rate from the per capita birth rate. This simplistic calculation does not factor in the effects of migration or immigration on a
The formula for calculating population density requires dividing the area occupied, typically in square miles or square kilometers, by the number of people living there. Though population density usually refers to people, the term also applies to animals in a particular habitat.
A human on the moon weighs approximately one-sixth of his weight on Earth, explains a "Math and Molecules" course text at New York University. Therefore, dividing a human's normal weight by six gives his approximate weight on the moon. For example, a 360-pound person weighs about 60 pounds on the mo
Causes of population increase include quality health care, increased food production, immigration, fight against poverty and lack of family planning. High population increase has negative impacts to the country, including conflicts, environmental degradation, high cost of living and reduction in nat
"Demography" is the name for the social science which concerns itself with studying populations. Specifically, it is the science of the social statistics of populations, such as births, deaths, diseases and marriages.
