Density measures how many people there are living in each hectare. Cazenga has very high population density: 306 people per hectare – a hectare is a little smaller than the size of a football field. Population density in Cazenga is more than double the density in Ingombota.

Some areas of the city are growing faster than others. Cazenga added a little more than 250,000 residents between 2000 and 2008. The population increased at a rate of 3.2%. This is a slower rate of growth than other areas of the city like Vianna where there is more open land for housing.
Development Workshop created a map of the buildings in Luanda. The map shows where new buildings have been constructed and where buildings have been demolished between 2008 and 2010. In the last few years, most new houses are being constructed in the eastern areas of Cazenga.

As open land has become scarce, some residents have built housing near vulnerable areas such as lagoons, gullies, and streams that often flood. There are 1,950 houses with 13,600 residents in these areas of risk in Cazenga.
Few residents in Cazenga have access to the public piped water system, so many obtain water at stand-pipes. This map shows the locations of stand-pipes in Hoji ya Henda and the areas within 100- and 200-meter walking distances from them. While many stand-pipes have been constructed, many families still have to walk far to access water.
Structures Added 2008 - 2010
Structures Demolished 2008 - 2010
Cazenga is growing everyday as people move to Luanda and come to the area to find employment and housing. The arrival of so many new people influences what kinds of housing are available, what streets are like, and whether people face physical risks.

Cazenga Atlas Survey
In 2012, the Forum surveyed over 3,000 households about basic services and the conditions of the built environment in Cazenga. The results of the survey are presented in the Cazenza Atlas along with other data collected by Development Workshop.
Population
Cazenga is located south-east of the center of the city and has over 1,250,000 residents, making it the fourth most populous municipality in Luanda.

Cazenga Age Pyramid
Cazenga has a “youth bulge” since over one-third of residents are under the age of 24. This means that there is a very large number of people who need education so that when the youth are older, they will have the skills required to find employment.

Water
Only 14% of residents have public water service in Cazenga. Most residents access water at standpipes where 95% of households pay more than the real price of 5 kwanza for a 20-liter container.
SOLUTION: AMOGECS are committees of residents who volunteer to manage stand-pipes. They contribute to selecting locations for stand-pipes and maintaining them so that residents have access to water. Local government is currently creating new household water connections that will benefit more than 10,000 houses in the first phase of the project.

Sanitation
Only 21% of households have a connection to a sewer system. This is slightly less than the proportion of households with sewer connections in Luanda as a whole.
SOLUTION: Between 2004 and 2006, local government, churches, and NGOs worked together to install latrines for households in Cazenga.

Housing
As more people move to Cazenga, physical vulnerability that results from high population density, overcrowding in housing, and living in vulnerable areas near lagoons and gullies increases. There are, for example, 1,950 homes in vulnerable areas that flood.

There are only nine public health facilities in Cazenga to serve over 1 million residents. Thirty percent of households reported cases of malaria among children during the previous month.
