Demography
Demography is the branch of sociology which studies the characteristics of human populations.
In biological terms it is the change in certain characteristics of populations of organisms of the same species
No, acquired characteristics, such as building muscles through exercise, can not be passed onto the progeny and thus allele can not change over time in populations from acquired characteristics. The are not " hard " heritability.
descent with modification
There are different methods for comparing the mean, variance or standard error, distribution or other characteristics of populations. Without more specific information it is not possible to answer the question.
A demographer studies shifts in the characteristics of populations. They study birth rates, death rates, and the age of the population.
Descent with modification
Whenever it is impractical to measure the characteristics of interest of each member of the population. For example, the populations of most countries are too large for any of the characteristics of all of the people within them to be measured. For that reason, sampling techniques are applied so that representative samples can be obtained of country populations.
Demographers study human population size, density and distribution, movemenet, and its birth and death rates
