Infrastructure in Dili continues to be developed. The city was the first location in East Timor to see 24 hours of electricity, although its water infrastructure remains relatively limited. Education levels are higher than the national average, and the country's universities are located in the city. An international port and airport lie within the city limits. Most economic activity comes from the tertiary sector and public employment. To further build the economy, the government is developing the tourism potential of the city, focusing on cultural, environmental, and historical attractions.
