Well, at least you got the word right.
Most people are aware of the influence of demographics on planning by business and government.
The hospital where my mother works had to commission a demographic study of the surrounding counties to prove the need for a new cardiac catheterization unit. Moreover, people see the effects of population change on the racial, ethnic and age composition of their neighborhoods, and worry about the effects of population increase on schools and quality of life. To put it broadly, demography is the study of human populations and the factors that affect them. Three basic processes shape every population, whether it be Vienna, Virginia, the United States, or Planet Earth. The first is fertility, the number of babies that are born.
