The study of vulnerability constitutes a central axis in research work on sustainability. Social vulnerability (SV) analyzes differences in human capacity to prepare, respond and recover from the impact of a natural hazard. Although disasters threaten all the people who suffer from them, they do not affect all members of society in the same way. Social and economic inequalities make certain groups more vulnerable. Factors such as age, sex, social class and ethnic identity increase vulnerability to a natural disaster.

This paper aims to analyze how the consequences of natural disasters affect gender relations in socioeconomic terms. To meet this objective, we quantitatively analyzed the effect of the earthquake that occurred in Haiti in 2010 based on data from the Demographic and Health Survey (DHS) developed by the United States Agency for International Development (USAID). To measure the impact of the 2010 earthquake we used the differences in differences (DID) technique.
