Quality education is a key factor to improve people's lives and to achieve sustainable development. Using data from PISA 2009, 2012 and 2015, in this paper the level of educational poverty of the Spanish regions is calculated by applying the Adjusted Bourguignon Chakravarty index, B C a (Sánchez-García et al. in Soc Indicat Res 145(2): 479–501). A descriptive analysis of the differences in educational poverty by gender and the contribution of each region and subject to the national level of educational poverty is also provided. This information could certainly be considered a starting point to tackle educational poverty in Spain.
