Because students often asked me where to find data, here I try to provide some resources that may help them find different sources or portals that can help you find different types of data.
If you know of any major portal with useful databases feel free to send me an email (firstname.lastname@example.org) with the link of the webpage and I would make it available for other students and researchers.
Portals to many sources of Micro Data (in Colombia and Developing countries):
Universidad de los Andes has put together a rich portal of microdata (and municipal level data) on Colombia:
