Zambia ranks 71 in population size, in comparison to other countries (China ranks first).
The ratio of males to females in Zambia is: 1.00 (this is the ratio of the entire population, in every age groups).
The number of males in Zambia is the same as the number of females. There are approximately 7,319,253 males and 7,319,253 females there.

Population Growth Rate
Population growth rate is 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.
The population growth rate in Zambia stands at 2.880 percent (2014 data).
Zambia is ranked 16 in the world in terms of population growth rate.
Zambia's population's growth rate is positive. It indicates that its population has grown at a rate of 2.880 percent per year (an increase of 421,589 people per year).
Birth rate is 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.
The birth rate in Zambia stands at an annual average of 42.46 per 1,000 people in the population (2014 data).
In terms of birth rate, this statistical datum places Zambia as no. 4 in the world.
This birth rate indicates that there are 621,551 births per year in Zambia.
Death rate is 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.
The death rate in Zambia stands at an annual average of 12.92 per 1,000 people in the population (2014 data).
In terms of death rate, this statistical datum places Zambia as no. 21 in the world in the world.
This death rate reveals that Zambia has 189,129 cases of death a year.
Net Migration Rate
Net migration rate is the difference between the number of persons entering and leaving a country during the year per 1,000 persons (based on midyear population). An excess of persons entering the country is referred to as net immigration; an excess of persons leaving the country as net emigration. The net migration rate indicates the contribution of migration to the overall level of population change. The net migration rate does not distinguish between economic migrants, refugees, and other types of migrants nor does it distinguish between lawful migrants and undocumented migrants.
The net migration rate of Zambia stands at -0.72 per 1,000.
This migration rate indicates that Zambia's population declines by about 10,540 people per year, as a result of migration.
The net migration rate of Zambia places it as no. 142 in the world.
Additional Population Characteristics
Median age is the age that divides a population into two numerically equal groups; that is, half the people are younger than this age and half are older. It is a single index that summarizes the age distribution of a population.
The median age of Zambia's population (male and female) is 16.7 years of age.
The median age of Zambia's male population in is 16.6.
The median age of Zambia's female population in is 16.8.
Urbanization And Urbanization Rate
About 39.2 percent of Zambia's population lives in urban areas; according to population size data in Zambia, the number of urban residents is around 5,738,294.
The population rate of urban areas in Zambia indicates that the urban population there has been growing by 4.15 percent per year.
