Demographics

Guatemala has a population of 17,608,483 (2021 est). With only 885,000 in 1900, this constitutes the fastest population growth in the Western Hemisphere during the 20th century. The Republic of Guatemala's first census was taken in 1778. The census records for 1778, 1880, 1893 and 1921 were used as scrap paper and no longer exist, although their statistical information was preserved. Censuses have not been taken at regular intervals. The 1837 census was discredited at the time; statistician Don Jose de la Valle made a calculation that in 1837 the population of Guatemala was 600,000. The 1940 census was burned. Data from the remaining censuses is in the Historical Population table below.

Guatemala is heavily centralized: transportation, communications, business, politics, and the most relevant urban activity takes place in the capital of Guatemala City, whose urban area has a population of almost 3 million.

The estimated median age in Guatemala is 20 years old, 19.4 for males and 20.7 years for females. Guatemala is demographically one of the youngest countries in the Western Hemisphere, comparable to most of central Africa and Iraq. The proportion of the population below the age of 15 in 2010 was 41.5%, 54.1% were aged between 15 and 65 years of age, and 4.4% were aged 65 years or older.
