The Katukina have experienced a population growth of approximately 80% over the last two decades. According to Funai’s data, the Katukina totalled 177 people in 1977: 100 in the village on the Gregório river and 77 in the village on the Campinas river. A little more than twenty years later in 1998, the Katukina possessed a total population of 318 people: 98 in the Gregório village and 220 in the Campinas village. In addition to the demographic growth, there has been an inversion in the relative size of the population between the villages.

Relocations from one village to another are fairly common and depend on the evaluations made by each Katukina individual concerning their social, economic and political situation at a particular moment in time. Today the Campinas village has more than twice the population of the Gregório village due to a large migratory flow to the former site taking place between 1994 and 1997.
