It is different from arithmetic population density, which simply refers to the number of people in a country divided by the size of the total land area of that country. Refugees are defined as people who are being forced to leave their traditional lands due to persecution or material hardship within their society. Common causes of major refugee movements are natural disasters, warfare , and political alienation or persecution.

factors do not record populations in this way, however, so equation is of limited usefulness in regional population studies. Statistical data on populations is compiled from CENSUSES of population and records of births, See DEMOGRAPHIC TRANSITION. This basic equation can be applied to populations and subpopulations. For example, the population size of ethnic groups or nationalities within a given society or country is subject to the same sources of change as the national population. However, when dealing with ethnic groups, “net migration” might have to be subdivided into physical migration and ethnic re-identification . Individuals who change their ethnic self-labels or whose ethnic classification in government statistics changes over time may be thought of as migrating or moving from one population subcategory to another.

Estimation of population coverage in the 1990 United States census based on demographic analysis.

We’ve got potholes to fix, and we need to know how many taxpayers there are. We’re going to have to pay for public schools, and we need to predict the number of We’ve got to stock health clinics, post offices, and government offices with enough people and supplies to meet the public’s needs. A “diaspora” is the name given to a community of people who are dispersed throughout the world, but retain their cultural, religious, or ethnic differences. The term is most commonly applied to Jewish people and to African-Americans in the United States. The number of refugees did not increase during this time period.

] the science dealing with populations, including matters of health, disease, births, and mortality. It is a kind of document that is integral to accounting for its function as the financial statement reporting a business organisation’s shareholder equity, assets, and liabilities. Natural increase is calculated by the fertility rate minus the mortality rate. Hence, the equation can also be used to analyze a decline in real GDP as well as an increase in real GDP. However, one problem with the formula is that the growth rate of technology is very difficult to accurately measure. Its calculation generally depends on the discretion of the accountant. Demographic Analysis Demographic analysis is a technique used to develop an understanding of the age, sex, and racial composition of a population and how it has changed over time.

Population geographers collect demographic data and use mathematical equations to understand trends in population growth and to make predictions about the future. Population growth and population density both vary dramatically over space—some countries are not growing at all, while others are doubling their populations every couple of decades. The fastest-growing countries are also among the poorest, and in many cases rapid population growth has led to severe environmental degradation and human suffering. However, environmental problems are not simply a function of population growth; they also result from the overconsumption of resources. Conse­quently, issues regarding population, consumption, social justice, and environmental sustainability provide geographers with many fascinating and complex ­questions.

The demographic balancing equation calculates the changes in a population over time. Learn the different factors that are studied in this calculation such as natural increase, net migration, and total population. As anyone living in the United States should realize, people enter this country in more ways than just birth and leave in other ways besides death. After all, what kind of melting pot would we be without all the world’s peoples? Net migration counts the total number of immigrants who enter an area and emigrants who leave.

As long as the final net worth figure and the amount of liabilities balance with the assets, all is well. It can be a very general science that can be applied to any kind of dynamic living population, or one that changes over time or space. It encompasses the study of the size, structure, and distribution of these populations, and spatial and/or temporal changes in them in response to birth, migration, aging, and death. In other words, the size of the population at time t + x is equal to the population at time t plus the births, minus the deaths, plus the immigrants, minus the emigrants, during the interval of time x. This simple formula can be used to derive a variety of rates and statistics describing population change.
