Despite ongoing efforts by the Ministry of Domestic Security, crime has worsened in Antananarivo since 2009. Between 1994 and 1998, the city had an average of eight to twelve police officers for every 10,000 inhabitants; large cities typically have closer to fifteen. Under the mayorship of Marc Ravalomanana (1998–2001), street lights were installed or repaired throughout the city to improve night-time safety. He increased the number of police officers on the streets, leading to a drop in crime. , the city lacks a comprehensive strategy for reducing crime. The recent increase in crime and the inadequate response from the CUA has prompted the growth of private security firms in the city.
