Chad People Stats
Definitions
- Age distribution > Median age: The median age of the country's residents. This is the age most people are in the country.
- Age distribution > Population aged 0-14: Percentage of total population aged 0-14.
- Age distribution > Population aged 0-14 > Total: Number of people aged 0-14.
- Age distribution > Population aged 15-24 > Percent: Percentage of total population aged 15-24.
- Age distribution > Population aged 15-24 > Total: Number of people aged 15-24.
- Age distribution > Total dependency ratio: Percentage of dependant persons out of total population aged 15-64. A dependant person is a person aged 0-14 and those over 65 years old.
- Birth rate: The average annual number of births during a year per 1,000 persons in the population at midyear; also known as crude birth rate. The birth rate is usually the dominant factor in determining the rate of population growth. It depends on both the level of fertility and the age structure of the population.
- Death rate: The average annual number of deaths during a year per 1,000 population at midyear; also known as crude death rate. The death rate, while only a rough indicator of the mortality situation in a country, accurately indicates the current mortality impact on population growth. This indicator is significantly affected by age distribution, and most countries will eventually show a rise in the overall death rate, in spite of continued decline in mortality at all ages, as declining fertility results in an aging population.
- Ethnic groups: This entry provides a rank ordering of ethnic groups starting with the largest and normally includes the percent of total population.
- Gender > Female population: Total female population.
- Mother's mean age at first birth: This entry provides the mean (average) age of mothers at the birth of their first child. It is a useful indicator for gauging the success of family planning programs aiming to reduce maternal mortality, increase contraceptive use – particularly among married and unmarried adolescents, delay age at first marriage, and improve the health of newborns.
- Population: Population, total refers to the total population.
- Population > Population growth, past and future: Population growth rate (percentage).
- Population growth: Percentage by which country's population either has increased or is estimated to increase. Countries with a decrease in population are signified by a negative percentage. Future estimates are from the UN Population Division.
- Population growth rate: The average annual percent change in the population, resulting from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country. The rate may be positive or negative. The growth rate is a factor in determining how great a burden would be imposed on a country by the changing needs of its people for infrastructure (e.g., schools, hospitals, housing, roads), resources (e.g., food, water, electricity), and jobs. Rapid population growth can be seen as threatening by neighboring countries.
