Future of World Religions in 2050

What do you need to know about the future of world religions? By 2050, the number of Muslims around the world will nearly equal the number of Christians. That’s since Islam will grow faster than any other major world religion. This video shows the future statistics of adherents to the world religions in 2050.

Populations can change through three processes: fertility, mortality, and migration. Fertility involves the number of children that women have and demographers contrast it with fecundity (a woman’s childbearing potential).

Mortality is the study of the causes, consequences, and measurement of processes affecting death to members of the population. Demographers most commonly study mortality using the Life Table; a statistical device which 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 political boundary. Migration researchers don’t designate movements ‘migrations’ unless they are somewhat permanent. Thus demographers don’t consider tourists and travellers to be migrating. Demographers who study migration typically do so through census data on place of residence. However, indirect sources of data including tax forms and labour force surveys are also important.

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.

Population institutions are part of the International Committee for Coordination of Demographic Research network. On the other hand, most individual demographers are members of the International Union for the Scientific Study of Population.

Important Scientific Field

Demography is the statistical study of populations, especially human beings. As a very general science, it can analyze any kind of dynamic living population, i.e., one that changes over time or space (see population dynamics).

Demography encompasses the study of the size, structure, and distribution of these populations, and spatial or temporal changes in them in response to birth, migration, aging, and death.

Based on the demographic research of the earth, earth’s population up to the year 2050 and 2100 can be estimated by demographers. Demographics are quantifiable characteristics of a given population.

Demographic analysis can cover whole societies or groups defined by criteria such as education, nationality, religion, and ethnicity.

Formal demography limits its object of study to the measurement of population processes, while the broader field of social demography or population studies also analyses the relationships between economic, social, cultural, and biological processes influencing a population.
