What was the population of the areas annexed by the US from Mexico in the 1840s? Basically, "Texas," "California" and the area in between?
I can only find figures excluding Indians. According to Weber's The Mexican Frontier, California had 7,300 in 1845, and New Mexico had 65,000 in 1846. Texas in 1846, according to the Texas State Historical Association, had 125,000 people.
