World demographics include population, growth rates, median age, and statistics for individual countries. Economists use them to predict economic trends, while census statisticians collect data for population reporting. Population growth rates and median age provide insight into economic, cultural, and historical changes, while gender and other subdivisions provide additional statistical evidence.
World demography refers to various identifiable attributes of the world’s population. Statistics associated with world demographics include population, population growth rates, and median age. Other global demographics include population statistics for individual countries, such as the average number of people retired and life expectancy.
Various organizations and professions use world demographic statistics. Economists use them to predict future economic trends related to national wealth and income. Census statisticians collect data for population reporting to help governments formulate budgets and identify specific trends related to both local and worldwide growth.
Global population statistics are typically the world’s most talked about demographic data. The population of each country and the global community contribute to this data. In particular, the overall population is used as a basis for further revision of the numbers. If plotted over time, this information can provide insight into the effect of population growth on the global economy.
Population growth rates are calculated by analyzing the change in the total population over a specified period of time. By comparing population change over a given time period, economists and others can analyze the impact of economic, cultural, or historical changes that also occurred during the same time period. This may also include observing change in specific age groups, such as young people and the elderly.
Another type of world demography is the median age of the population. The age of a given population can provide insight into population decline related to health, wealth, and vitality. The age of a population provides a wealth of information, such as the average birth rate and average life expectancy. Global and regional life expectancy can be analyzed to determine the underlying cause of longer life, such as diet or cultural practices.
The gender of the current world population is another example of world demography. This statistic provides information about the percentage of males and females in the total world population. Gender can also be used in conjunction with median age and life expectancy to infer additional statistical evidence regarding which gender lives the longest.
You can find a number of other statistics relating to world demographics. Economists look at trends in retirement age when discussing a country’s future wealth or overall global population. Other subdivisions of the global population provide demographic data such as the percentage of various races and religions that exist worldwide.
