Demographics are used by researchers all over the world to study different aspects of populations. Different researchers use different statistical techniques and models to create demographic maps. A demographic is simply a description of a specific group of individuals. Researchers usually study whole societies or even smaller groups of individuals. Some examples of demographic studies are sex, age, education, marital status, income, ethnicity or religion, to name only a few.
Demography can also be used to predict an individual’s likelihood of marrying and reproducing. With this information, researchers can design laws and programs that will affect demographics in future generations. For example, if future generations have low educational levels, then family size may be reduced and family norms will be changed as children become less aggressive and dependent on their parents. Similarly, if future generations have high educational levels and low family sizes, then families will be able to pro-create more children. Demographic mapping can also be used to study religious demographics.
Demographics allow researchers to track the characteristics of certain groups over time. Demographic map by zip code can also be used to analyze cultural, social and economic trends. Demographic analysis can provide insights about changing consumer preferences and behaviors. Demographics can even provide data about national sentiments regarding particular groups or sub-groups within a country or state. These facts can help researchers understand how public policies affect individuals within a certain demographic segment.
