Through presence or absence, indigeneity has long been at the center of Bolivian politics, culture, and nationalism.1 It carries immense social import. Yet what Indigenous means and who gets counted as part of this umbrella category has never been clear or static. Although Bolivia's racial and ethnic categories seem as etched in stone as the Andes themselves, individual classification is fluid and situational based on sociocultural markers that change over time. These markers include occupation, literacy, dress, language, surname, and residence. Individuals may move through these categories (and not only in one direction) over the course of their lives. This fluidity, combined with changing meaning and the valorization of indigeneity at the national and international levels, has led to wild fluctuations in official statistics on race since independence. The social construction of these categories came to the fore in 2012 when the census reported that Bolivians who identified as Indigenous had dropped to 40 percent of the population, down from 62 percent only eleven years earlier. International observers were left wondering, where did all the Indigenous people go?2
