This article characterizes the conditions of the informal land and housing supply during the first decade of the xxi century in Bogota, regarding magnitude and location of the informal urban growth (new occupations in the periphery and informal densification of consolidated areas), housing conditions in recent occupations and the characteristics of the land market. The situation of the last decade has been reconstructed based in aerial photography analysis, census data quantification and data analysis from planning and control public entities. Results suggest that due to the relative land scarcity in Bogota, among other aspects, the informal market dynamics have experimented changes compared to previous decades, because the growth in consolidated urban areas becomes more important than the informal urbanization of the peripheries, but at the same time informality transcends the municipal perimeter to the neighboring municipalities.
