Global Population: Overview
The entire number of people living in a nation or area is referred to as its population. The economy, female fertility rates, birth rates, mortality rates, healthcare facilities, expanding urbanization, immigration and emigration rates, education, and other social and cultural elements are only a few of the many variables that affect a nation's population growth.
Currently, the global population is growing at a low single-digit annual rate. The population is projected to grow by 81 million people annually. The population of the world has more than doubled between 1959 and the 2000s. The annual rate of population increase reached its high in the late 1960s. The pace of increase has nearly halved since then, and it is anticipated that it will continue to decrease globally in the coming years.
Iceland Population Distribution
The population of Iceland reached 0.4 million in 2021. Iceland had the largest population group with 66.8% (0.25 million) of the population falling into the working-age group of 15-64 years. Below 15 years, was the second-largest population group in Iceland with 18.6% (0.07 million) of the population. 65 years and above was the third largest population group with 14.6% (0.05 million) of the total population in 2021.
According to GlobalData, the population is expected to grow at an average annual rate of 1.3% over 2021–23. Iceland’s population is aging due to its declining birth rate (15.3 births per 1,000 population in 2000 to 12.6 in 2020) and continued improvements in life expectancy (79.7 years in 2000 to 83.2 years in 2020). With the country's older population increasing every year and expected to reach 15.8% of the total population by 2025, the cost of social welfare is expected to rise.
Iceland's aging population has increased, following the trend of other European countries. This will lead to a decline in the workforce. In 2020, the working-age population accounted for 66.9% of the total population and the old-age population accounted for 14.4%. Male and female populations in Iceland recorded low single-digit annual increase.
