Demographics
With an estimated 46 million people in 2008, Colombia is the third-most populous country in Latin America, after Brazil and Mexico. It is also home to the third-largest number of Spanish speakers in the world after Mexico and Spain. It is slightly ahead of Argentina by almost 6 million people. At the outset of the 20th century, Colombia's population was approximately 4 million. The population increased at a rate of 1.9% between 1975 and 2005, predicted to drop to 1.2% over the next decade. Colombia is projected to have a population of 50.7 million by 2015. These trends are reflected in the country's age profile. In 2005 over 30% of the population was under 15 years old, compared to just 5.1% aged 65 and over.
The population is concentrated in the Andean highlands and along the Caribbean coast. The nine eastern lowland departments, comprising about 54% of Colombia's area, have less than 3% of the population and a density of less than one person per square kilometer (two persons per square mile). Traditionally a rural society, movement to urban areas was very heavy in the mid-20th century, and Colombia is now one of the most urbanized countries in Latin America. The urban population increased from 31% of the total in 1938 to 60% in 1975, and by 2005 the figure stood at 72.7%. The population of Bogotá alone has increased from just over 300,000 in 1938 to approximately 8 million today. In total seventy one cities now have populations of 100,000 or more (2013). As of 2010 Colombia has the world's largest populations of internally displaced persons (IDPs), estimated up to 4.5 million people.
