Demografické

Demografické is a Czech term used as an adjective meaning "demographic" or "pertaining to demography." In Czech-language texts it appears in phrases such as demografické údaje (demographic data), demografické změny (demographic changes), or demografická struktura obyvatel (population age structure). It is often contrasted with demografie, the science that studies population characteristics.

Demography, or demografie in Czech, studies the size, structure, and distribution of populations, as well as the processes that affect them, including fertility, mortality, and migration. It analyzes how age, sex, ethnicity, and geographic location interact to shape population dynamics.

Key indicators include birth rate, total fertility rate, mortality rate, life expectancy, age pyramids, dependency ratios, and net migration. Data come from censuses, vital statistics, and household surveys. Limitations include undercounting, sampling errors, and inconsistent definitions across countries.

Knowledge of demografické patterns informs public policy, economics, urban planning, healthcare, and social services. It explains trends such as aging populations, urbanization, and regional disparities. Businesses also use demographic data for market analysis and planning.

In Czech usage, the term appears in many compound forms, such as demografické trendy (demographic trends) or demografické projekce (demographic projections). It is a standard element of statistical and scientific writing about populations.
