Colombia experiences significant legal and illegal economic emigration and refugee flows. Large-scale labor emigration dates to the 1960s; Venezuela and the United States continue to be the main host countries. Colombia is the largest source of Latin American refugees in Latin America, nearly 400,000 of whom live primarily in Venezuela and Ecuador. Forced displacement remains prevalent because of violence among guerrillas, paramilitary groups, and Colombian security forces. Afro-Colombian and indigenous populations are disproportionately affected. A leading NGO estimates that 5.2 million people have been displaced since 1985, while the Colombian government estimates 3.6 million since 2000. These estimates undercount actual numbers because many internally displaced persons are not registered. Columbia also has one of the world's highest levels of forced disappearances. About 30,000 cases have been recorded over the last four decades - although the number is likely to be much higher - including human rights activists, trade unionists, Afro-Colombians, indigenous people, and farmers in rural conflict zones.
- Age distribution > Population aged 0-14: Percentage of total population aged 0-14.
- Age structure > 0-14 years: The distribution of the population according to age. Information is included by sex and age group (0-14 years, 15-64 years, 65 years and over). The age structure of a population affects a nation's key socioeconomic issues. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to unrest.

- 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.
- Obesity > Adult obesity rate: This entry gives the percent of a country's population considered to be obese. Obesity is defined as an adult having a Body Mass Index (BMI) greater to or equal to 30.0. BMI is calculated by taking a person's weight in kg and dividing it by the person's squared height in meters.
- 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.
- Population in 2015: (Thousands) Medium-variant projections.
- Urban and rural > Population living in cities proper: City population by sex, city and city type.
