What was mexicos population in 1800s?

Answer 1

Today's Mexico was in 1800 a part of the Spanish viceroyalty of New Spain, incorporating the nominally subject regions of Central America (Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica), Cuba, Puerto Rico, the Philippines, several smaller island territories and much of what is now the southwestern United States (California, Nevada, Utah, Texas and parts of Colorado, Arizona, New Mexico and Wyoming), and with a combined population of around 10 million.

The territory which in 1821 became independent Mexico - i.e, excluding the island dependencies but including Central America (until 1823) and the areas lost or ceded to the US in 1836-54 - in 1800 contained nearly 7 million people.

The population in 1800 of the present-day republic of Mexico has been estimated at 5.1 million on the basis of the census conducted in the early 1790s, adjusted for omissions and intervening growth. The scale and scope of under-enumeration however remain unclear from the original returns, and a slightly higher figure may be appropriate.

Answer 2

The 19th century was a difficult time for Mexico. It had to go through several civil wars, foreign invasions by France and the United States, and suffered a loss of half its territory. Its population barely changed throughout such century. Population estimates are as follows:

1800: 4 million

1825: 6.8 million

1846: 7.5 million (right before the Mexican-American War)

1858: 8.3 million

1872: 9 million

1876: 9.5 million

1899: 13.6 million
