In 1986, the Institut Haitien de Statistique et d'Informatique (IHSI) with support from the U.S. Agency for International Development (USAID) implemented a nationwide Household Expenditure and Consumption Survey (HECS) to gather socioeconomic data to analyze nutrition, health, welfare, food pricing policies, and other issues related to Title III, and to provide IHSI with data to calculate consumer price indexes and national accounts. Data were gathered from November 1986 through September 1987.
