Nigeria is the most populous country in Africa and the sixth most populous in the world. It is also one of the most densely populated countries in Africa, with approximately 218.5 million people in an area of 923,768 km2 (356,669 sq mi).
Venezuela is a country in South America. The Venezuelan people comprise a combination of heritages, primarily Native American and European. The historically present Native American, Spanish colonists, and African slaves have all contributed to varying degrees. Later, waves of European groups migrated to Venezuela in the 20th century, influencing many aspects of Venezuelan life, including its culture, language, food, and music though small in number.

The demographic characteristics of the population of The Gambia are known through national censuses, conducted in ten-year intervals and analyzed by The Gambian Bureau of Statistics (GBOS) since 1963. The latest census was conducted in 2013. The population of The Gambia at the 2013 census was 1.8 million. The population density is 176.1 per square kilometer, and the overall life expectancy in The Gambia is 64.1 years. Since the first census of 1963, the population of The Gambia has increased every ten years by an average of 43.2 percent. Since 1950s, the birth rate has constantly exceeded the death rate; the natural growth rate is positive. The Gambia is in the second stage of demographic transition. In terms of age structure, The Gambia is dominated by 15- to 24-year-old segment (57.6%). The median age of the population is 19.9 years, and the gender ratio of the total population is 0.98 males per female.
In demography, demographic transition is a phenomenon and theory which refers to the historical shift from high birth rates and high death rates to low birth rates and low death rates, as societies attain more technology, education and economic development. The demographic transition has occurred in most of the world over the past two centuries, bringing the unprecedented population growth of the post-Malthusian period, then reducing birth rates and population growth significantly in all regions of the world. The demographic transition strengthens economic growth process by three changes: (i) reduced dilution of capital and land stock, (ii) increased investment in human capital, and (iii) increased size of the labor force relative to the total population and changed age population distribution. Although this shift has occurred in many industrialized countries, the theory and model are frequently imprecise when applied to individual countries due to specific social, political and economic factors affecting particular populations.
The dependency ratio is an age-population ratio of those typically not in the labor force and those typically in the labor force. It is used to measure the pressure on the productive population.
Population decline, also known as depopulation, is a reduction in a human population size. Throughout history, Earth's total human population has continued to grow; however, current projections suggest that this long-term trend of steady population growth may be coming to an end.
Population ageing is an increasing median age in a population because of declining fertility rates and rising life expectancy. Most countries have rising life expectancy and an ageing population, trends that emerged first in developed countries but are now seen in virtually all developing countries. In most developed countries, the phenomenon of population aging began to gradually emerge in the late 19th century. The aging of the world population occurred in the late 20th century, with the proportion of people aged 65 and above accounting for 6% of the total population. This reflects the overall decline in the world's fertility rate at that time. That is the case for every country in the world except the 18 countries designated as "demographic outliers" by the United Nations. The aged population is currently at its highest level in human history. The UN predicts the rate of population ageing in the 21st century will exceed that of the previous century. The number of people aged 60 years and over has tripled since 1950 and reached 600 million in 2000 and surpassed 700 million in 2006. It is projected that the combined senior and geriatric population will reach 2.1 billion by 2050. Countries vary significantly in terms of the degree and pace of ageing, and the UN expects populations that began ageing later will have less time to adapt to its implications.
A population pyramid or "age-sex pyramid" is a graphical illustration of the distribution of a population by age groups and sex; it typically takes the shape of a pyramid when the population is growing. Males are usually shown on the left and females on the right, and they may be measured in absolute numbers or as a percentage of the total population. The pyramid can be used to visualize the age of a particular population. It is also used in ecology to determine the overall age distribution of a population; an indication of the reproductive capabilities and likelihood of the continuation of a species. Number of people per unit area of land is called population density.
Demographic dividend, as defined by the United Nations Population Fund (UNFPA), is "the economic growth potential that can result from shifts in a population’s age structure, mainly when the share of the working-age population is larger than the non-working-age share of the population ". In other words, it is "a boost in economic productivity that occurs when there are growing numbers of people in the workforce relative to the number of dependents". UNFPA stated that "a country with both increasing numbers of young people and declining fertility has the potential to reap a demographic dividend."
The ageing of Europe, also known as the greying of Europe, is a demographic phenomenon in Europe characterised by a decrease in fertility, a decrease in mortality rate, and a higher life expectancy among European populations. Low birth rates and higher life expectancy contribute to the transformation of Europe's population pyramid shape. The most significant change is the transition towards a much older population structure, resulting in a decrease in the proportion of the working age while the number of the retired population increases. The total number of the older population is projected to increase greatly within the coming decades, with rising proportions of the post-war baby-boom generations reaching retirement. This will cause a high burden on the working age population as they provide for the increasing number of the older population.
In demography, replacement migration is a theory of migration needed for a region to achieve a particular objective. Generally, studies using this concept have as an objective to avoid the decline of total population and the decline of the working-age population.
Earth has a human population of over 8 billion as of 2024, with an overall population density of 50 people per km2. Nearly 60% of the world's population lives in Asia, with more than 2.8 billion in the countries of India and China combined. The percentage shares of China, India and rest of South Asia of the world population have remained at similar levels for the last few thousand years of recorded history. The world's literacy rate has increased dramatically in the last 40 years, from 66.7% in 1979 to 86.3% today. Lower literacy levels are mostly attributable to poverty. Lower literacy rates are found mostly in South Asia and Sub-Saharan Africa.
Human population projections are attempts to extrapolate how human populations will change in the future. These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. Models of population growth take trends in human development and apply projections into the future. These models use trend-based-assumptions about how populations will respond to economic, social and technological forces to understand how they will affect fertility and mortality, and thus population growth.
Population decline has many potential effects on individual and national economy. The single best gauge of economic success is growth in GDP per capita, not GDP. GDP per capita is an approximate indicator of average living standards, for individual prosperity. Therefore, whether population decline has a positive or negative economic impact on a country's citizens depends on the rate of growth of GDP per capita, or alternatively, GDP growth relative to the rate of decline in the population.
In demographic terms, aging refers to an increase in the proportion of senior citizens to the total population. The term "senior citizen" encompasses those aged 65 or older. In 2045, South Korea is projected to become the world's most aged population, surpassing Japan. Senior citizens will reach 46.5 percent of the population in 2067, outnumbering the working age population.
