In other words, population change refers to change in the number of people during a specific time period. As a whole,the world population has not been stable; it has increased manifold. Due to this constant changing population, the subject of demographics, the statistics of how many people there are in a given population, was created. Demography can also be defined as the study of populations, and the factors that cause the most amount of population growth or decline. The main measurements of demography include: birth rates, death rates, sex ratios, life expectancy, and migration rates. All of these measures are found by a series of surveys and censuses conducted over a time period in order to compare how the population is changing. of migration , birth and death of people.
