population is collection of the inter breeding organisms of a particular species in sociology, a collection of the human beings. Set of the data consisting of all conceivable observations of a certain phenomenon. Human populations defined as the mortality, migration, family, public health, work and the labor force and family planning. Population increase in the world was negligible until the Industrial Revolution. The population grew from about a quarter billion to a half billion persons. By the mid-19th cent, it had grown to about one billion and by 1930 it had risen to 2 billion, the United Nations estimates the all world population will peak at 10 billion in 2200. In the all world terms, the population is growing at about 1.2% annually compared with the 0.1% in ancient times and a rate of 1.75% as recently as the 1990s in the population graph.

Populations examples are:
1) number of defective and nondefective bolts produced in a factory on a given day.
2) heights and weights of students in a university.
3) all possible outcomes heads and tails in successive tosses of a coin.

Population growth of the all world In the late 20th cent, a major population difference arose in the comparative growth rates of the developed 0.6% and developing 2.1% nations. Africa's annual population growth rate is about 3%, compared to 1.7% for Asia, 0.7% in Latin America and the 0.3% in Europe. If the population graph increase currently this speed, many developing countries will double their populations in approximately 25 years or less, The populatin in 1800, 32.8 millions, in 1900 the populaion are 44.1, in 1950 the populaion are 79.2, in 1950 the populaion are 79.2, in 1975 the populaion are 154.3, in 2000 the populaion are 308.6 and the population rate approximately 449.3. The population would have risen at approximately the 1 percent per year.

Population control is the practice of limiting population increase, usually by reducing the birth rate. Population control is any methodology used to control the type, location and number of people that inhabit the earth. The practice has sometimes been voluntary, as a response to the poverty, environmental concerns or out of religious ideology. This is generally conducted to improve the quality of life for a society. Another method of population control is through the controlled migration. This is a method whereby large swaths of people are uprooted to the new locations. This can be done by a diffeent types of methods. 1) Economic providing the jobs and economic assistance to areas desirable for human migration. 2) War causing large scale military unrest where it is desired to have people migrate from such as regions rich in natural resources. 3) Disease using disease or the fear of disease to encourage migration. 4) Famine using famine as a means to induce people to migrate.
