Nevertheless, a more in-depth analysis shows that perceptions of distributive justice have varied in recent years. This may not suggests that these changes be associated exclusively with economic issues and with the crises that have occurred, but also with political and institutional arrangements that have been put in place during the past decade, and which, although they were initially expressed through intense social conflicts, later culminated in political responses that to a certain extent channelled the population’s principal demands. Another factor that might affect perception of distributive justice is the specific composition of the welfare regimes of certain countries, such as Costa Rica (see box 1.7). In addition, although the figure fell between 1997 and 2002, the proportion of the population that believed that income distribution was very unfair increased by 15% from 2002 to 2007, placing Chile in second place in the region (with 45% of the population believing in 2007 that distribution was very unfair), only behind Paraguay with 55%.
