He then used the methodology developed by Kraay (2004) to determine how much influence is exerted by each component of pro-poor growth and found that increases in income have been relatively more influential than changes in inequality as a source of pro-poor growth in the northeastern region of the country. Their findings indicated that growth in Brazil in the post-Real Plan period was indeed pro-poor. Their results suggest that all parts of the country experienced pro-poor growth in 1987-2007.
