PHASES AND FACES OF INTRASTATE MOBILITY AND MIGRANT SELECTION IN CEARÁ: EVIDENCE BETWEEN THE RMF AND THE INTERIOR (2010–2022)

Population redistribution between capital cities and inland cities has received increasing attention in demographic and urban studies. In Ceará, understanding whether there is a movement of population deconcentration from the RMF to the interior or, conversely, metropolitan expansion, or both, is essential to identify changes in the urban network and regional socioeconomic dynamics. Such transformations directly influence territorial planning, the provision of public services, and development strategies. Furthermore, analyzing migratory selectivity allows us to understand how attributes such as education, occupation, and income shape migration and territorial inequalities. This dissertation aims to analyze whether the state of Ceará is experiencing a process of demetropolization, with population displacement from the RMF to inland cities (differentiated by population size), or expanded metropolization, with redistribution around the Fortaleza Metropolitan Region (RMF), or both. It also investigates the extent to which intrastate migration flows, income differentials, and municipal size reveal new territorial arrangements and implications for urban networks and migrant selectivity. The analysis uses microdata from the 2010 and 2022 IBGE Demographic Censuses, considering two areas: the RMF (Regional Metropolitan Region) and the Interior (subdivided by population size categories). Migration flows are measured using an origin-destination matrix and indicators of Gross Migration, Net Migration, and the Migration Effectiveness Index. Selectivity is examined using an econometric income model with correction for selection bias, controlling for sociodemographic characteristics. The aim is to confirm two central hypotheses: (i) the advance of intrastate demetropolization, with a reduction in the attractiveness of the RMF, positive migration balances in the interior, especially in medium-sized cities, and the emergence of new centralities; and (ii) the positive selectivity of intrastate flows, with migrants having higher levels of education, formalization, and income than non-migrants. By articulating spatial changes and socioeconomic profiles, the research contributes to the understanding of territorial reconfigurations in Ceará and offers insights for public policies aimed at reducing regional inequalities and strengthening the state's urban network.
