Colombian Longitudinal Survey (ELCA)
ELCA is a longitudinal survey that follows 10,800 Colombian households: 6,000 urban and 4,800 rural, every three years. Its aim is to follow the same households for 12 years. The main objective of the survey is to better understand the social and economic changes that the households and their members experience. For this reason, ELCA provides information regarding households’ behaviour and its effects on their well-being. ELCA is the first survey of this type that has been undertaken in Colombia, and that has, as of 2024, three rounds: the baseline in 2010, the first follow-up round in 2013, and the second follow-up round in 2016.

Representative sample at baseline?
The urban sample is nationally representative of Colombia, by geographic region, and by socioeconomic strata (including only Strata 1-4 and excluding Strata 5 and 6, which comprise the richest households). The rural sample is only representative of four specific micro-regions of the country.
