Terms and Definitions

Population refers to the total number of individuals residing in a specific geographic area. This can apply to various sizes—from a global scale to specific territories like countries, regions, cities, or towns. Population size is one of the standard measures of a place's scale and capacity, often used in data analysis and planning.

A Census is an official, typically government-led, count of citizens or residents within a specific country or region. It is usually conducted at regular intervals and involves collecting various demographic information including age, sex, occupation, etc. Census data is vital for the planning of public services and understanding the demographic characteristics of a country.

Demographics refers to the statistical information of a population. This typically includes gender, age, ethnicity, income level, education, etc. These are used for market research, public policy planning, and social research. It helps in understanding the characteristics and behavior of a group of humans in a given location.

Population Density is a measurement of population per unit area or unit volume. In its basic sense, it is calculated as the number of people per square kilometer or mile. This can be a key indicator of overpopulation, distribution of resources, and how crowded a country or region may be.

Population Growth Rate represents the pace at which the number of inhabitants in a country increases (or decreases) over a given period of time, typically annualy. It's expressed as a percentage and considers factors such as births, deaths, and net migration.

Birth Rate, typically given per 1,000 people of an overall population in a year, refers to the annual number of live births. It is a crucial factor in calculating population growth.

Similar to birth rate, Death Rate is the number of deaths occurring per 1,000 individuals in a population, per year. It along with birth rate and migration rate influence population size and growth.

Fertility rate is the average number of children born to a woman over her lifetime in a population. It is an indicator of the reproduction level and potential growth rate of a population.
