Regardless of the possible inaccuracies related to the counting of Indigenous peoples living outside of the colonized areas, the effort that New Spain's authorities put into considering them as subjects is worth mentioning, as censuses made by other colonial or post-colonial countries did not consider American Indians to be citizens or subjects; for example, the censuses made by the Viceroyalty of the Río de la Plata would only count the inhabitants of the colonized settlements.[149] Another example is the censuses made by the United States, which did not include Indigenous peoples living among the general population until 1860, and indigenous peoples as a whole until 1900.[150]
