Between the 1930s and 1960s, Tegucigalpa continued to grow reaching a population of over 250,000 people, giving way to what would become one of the biggest neighborhoods in the city, the ''Colonia Kennedy''; the nation's autonomous university, the UNAH; and the construction of the ''Honduras Maya Hotel''.  It still remained relatively small and provincial until the 1970s, when migration from the rural areas began in earnest. During the 1980s, several avenues, traffic overpasses, and large buildings were erected, a relative novelty to a city characterized until then by two-story buildings.  However, lacking the enforcement of city planning and zoning laws, it led to highly disorganized urbanization.  This lack of proper urbanization as the population has grown is evident on the surrounding slopes of the several hills in the city where some of the city's most impoverished neighborhoods have prevailed.
