Terms and Definitions

Population refers to the total number of individuals living in a particular region at a specific time. It's a fundamental notion in demographics, primarily utilized in the field of sociology, where it's used to analyze topics like public health, education, economy, and environment.

A census is a comprehensive statistical counting process carried out by a country's government at regular intervals, typically every 10 years. It involves systematic data gathering about the members of the population, including details like age, gender, occupation, and household statistics.

Demographics are statistical data relating to the population and their specific groups within it, often segmented by factors such as age, ethnicity, income, education, and employment. It is used principally in sociology, marketing, and in the study of human populations.

Birth rate is an essential demographic concept that denotes the number of live births per 1,000 individuals in a population in a particular year. It is a major component in the calculation of population growth.

Death rate, also known as mortality rate, is the measure of the number of deaths in a particular population, scaled to the size of that population per unit of time. It's usually counted per year, per 1,000 people.

Migration is the process of people moving from one place to another with intentions of settling, permanently or temporarily, at a new location. It can occur over long distances as in between countries or it can happen over short distances as in between neighboring cities or states.

Population density represents the number of people living in a unit area of a region, such as per square kilometer or per square mile. It is used to show the concentration of population in a specific region.

Population growth rate is the rate at which the number of inhabitants in a population increases as a result of the balance between births, deaths, and migration during a particular period of time. It's frequently expressed as a percentage of the population.

Ethnicity refers to the characteristics that people identify with or are identified by others as representing a common and distinctive social group. These characteristics may include shared history, language, culture, ancestry, or a mixture of these.
