This is quite a feat given that for all of human history up until the 18th Century, all countries were considered within Stage 1.

There are two statistics that are fundamental in the study demography - birth rate and death rate. It is Population Education provides K teachers with innovative, hands-on lesson plans and professional development to teach about human population growth and its effects on the environment and human well-being.

These compare the sex ratios from the census data to those estimated from natural values and mortality data. Censuses do more than just count people. They may also collect data on migration or place of birth or of previous residence , language, religion, nationality or ethnicity or race , and citizenship. In countries in which the vital registration system may be incomplete, the censuses are also used as a direct source of information about fertility and mortality; for example the censuses of the People's Republic of China gather information on births and deaths that occurred in the 18 months immediately preceding the census.

Indirect methods of collecting data are required in countries and periods where full data are not available, such as is the case in much of the developing world, and most of historical demography. One of these techniques in contemporary demography is the sister method, where survey researchers ask women how many of their sisters have died or had children and at what age. With these surveys, researchers can then indirectly estimate birth or death rates for the entire population. Other indirect methods in contemporary demography include asking people about siblings, parents, and children. Other indirect methods are necessary in historical demography. There are a variety of demographic methods for modelling population processes.

They include models of mortality including the life table , Gompertz models , hazards models , Cox proportional hazards models , multiple decrement life tables , Brass relational logits , fertility Hernes model , Coale -Trussell models, parity progression ratios , marriage Singulate Mean at Marriage, Page model , disability Sullivan's method , multistate life tables , population projections Lee-Carter model , the Leslie Matrix , and population momentum Keyfitz. The United Kingdom has a series of four national birth cohort studies, the first three spaced apart by 12 years: the National Survey of Health and Development, the National Child Development Study , [15] the British Cohort Study , [16] and the Millennium Cohort Study , begun much more recently in These have followed the lives of samples of people typically beginning with around 17, in each study for many years, and are still continuing.

As the samples have been drawn in a nationally representative way, inferences can be drawn from these studies about the differences between four distinct generations of British people in terms of their health, education, attitudes, childbearing and employment patterns. A stable population does not necessarily remain fixed in size. It can be expanding or shrinking. Note that the crude death rate as defined above and applied to a whole population can give a misleading impression.

For example, the number of deaths per 1, people can be higher for developed nations than in less-developed countries, despite standards of health being better in developed countries. This is because developed countries have proportionally more older people, who are more likely to die in a given year, so that the overall mortality rate can be higher even if the mortality rate at any given age is lower. A more complete picture of mortality is given by a life table , which summarizes mortality separately at each age. A life table is necessary to give a good estimate of life expectancy.

Suppose that a country or other entity contains Population t persons at time t. These basic equations can also be applied to 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. When dealing with ethnic groups, however, "net migration" might have to be subdivided into physical migration and ethnic reidentification assimilation. 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.

More generally, while the basic demographic equation holds true by definition, in practice the recording and counting of events births, deaths, immigration, emigration and the enumeration of the total population size are subject to error. So allowance needs to be made for error in the underlying statistics when any accounting of population size or change is made. The UN "medium" projection shows world population reaching an approximate equilibrium at 9 billion by Working independently, demographers at the International Institute for Applied Systems Analysis in Austria expect world population to peak at 9 billion by Populations can change through three processes: fertility, mortality, and migration. Fertility involves the number of children that women have and is to be contrasted with fecundity a woman's childbearing potential.

Demographers most commonly study mortality using the Life Table , a statistical device that provides information about the mortality conditions most notably the life expectancy in the population. Migration refers to the movement of persons from a locality of origin to a destination place across some predefined, political boundary. Migration researchers do not designate movements 'migrations' unless they are somewhat permanent. Thus demographers do not consider tourists and travellers to be migrating. While demographers who study migration typically do so through census data on place of residence, indirect sources of data including tax forms and labour force surveys are also important.

Demography is today widely taught in many universities across the world, attracting students with initial training in social sciences, statistics or health studies. Being at the crossroads of several disciplines such as sociology , economics , epidemiology , geography , anthropology and history , demography offers tools to approach a large range of population issues by combining a more technical quantitative approach that represents the core of the discipline with many other methods borrowed from social or other sciences. Demographic research is conducted in universities, in research institutes as well as in statistical departments and in several international agencies.

Population institutions are part of the Cicred International Committee for Coordination of Demographic Research network while most individual scientists engaged in demographic research are members of the International Union for the Scientific Study of Population , [24] or a national association such as the Population Association of America in the United States, [25] or affiliates of the Federation of Canadian Demographers in Canada.
