Final answer:
One economical difference was economic domination, one social difference was the creation of a mestizo society, and one political difference was the dominance of Texans in local government.
Step-by-step explanation:
One economical difference between the Mexican and Anglo population was the economic domination experienced by Mexico at various times. This involved control of the land, economy, and political system, which created conflict and tension between the two groups. On the social front, a major difference was the mixing and acculturation of the Europeans and Amerindians in Mexico, resulting in the creation of a mestizo mainstream society. Lastly, a political difference was the dominance of Texans in local government, which threatened the Mexican government and the tejanos, leading to political tensions and conflicts.
