It depends on whether the purpose is to study current or past trends. The timeframe can be a guide: over a couple of generations, it's likely to be plain demography to inform the present; over a century or more, it's more likely historical demography to understand the past.
Geographers study population trends to understand how human populations are distributed, how they are growing or declining, and the impacts of these trends on the environment and society. This helps in making informed decisions about resource allocation, urban planning, and sustainable development. It also provides insights into social, economic, and political dynamics at different scales.
The population will increase in variety over time.

To understand how the study of history has changed over time
Population dynamics is considered a form of demography. Demography is the study of statistics of human populations. Population dynamics focuses on how those populations change over time, specifically.
you can use sampling when your population under study is large, expensive and time time consuming to study.... in a nut shell, when studying entire population is expensive we go for sampling...
cycles in population size over time; repeating changes in population size over time
the study of how artifacts and objects decay over an extended period of time
Geographers study a range of population statistics, including the total number of people in a given area, population density, birth and death rates, migration patterns, age structure, gender distribution, and population growth or decline over time. They also analyze factors such as urbanization, fertility rates, life expectancy, and social and economic implications of population dynamics.
Climatology is the study of climate and how it changes over time.
