Chile's 2017 census reported a population of 17,574,003 people. Its rate of population growth has been decreasing since 1990, due to a declining birth rate. By 2050 the population is expected to reach approximately 20.2 million people, at which point it is projected to either stagnate or begin declining. About 85% of the country's population lives in urban areas, with 40% living in Greater Santiago alone. The largest agglomerations according to the 2002 census are Greater Santiago with 5.6 million people, Greater Concepción with 861,000 and Greater Valparaíso with 824,000.
