Accounting for intragenerational mobility on poverty and inequality

Jeronimo O. Muniz, Universidade Estadual de Campinas (UNICAMP)

The overall objective of this chapter is to measure net intragenerational mobility between income classes in Brazil using demographic projection methods. Specific aims are twofold: (1) to suggest a method to calculate intragenerational net mobility using the residual difference between projected and observed censual populations. The main advantage of this approach is to estimate net mobility by age using only cross-sectional data by income class; (2) to estimate how income-specific net mobility has changed between 1980 and 2000 in Brazil in the presence of concurrent fertility and mortality declines. More specifically, this chapter will demonstrate the importance of social mobility vis-à-vis demographic changes in the determination of poverty. I identify the ages and income classes at which net mobility is positive, or negative, and describe the age standard of mobility and mortality in two periods, between 1980 and 1990, and between 1990 and 2000.
