For example, UN-Habitat's City Prosperity Initiative has over 450 cities with 72 urban- indicator data points available, and this has been complemented by other global data from 200 cities from the Global Sample of Cities. This helps city mangers to assess the urban policy implications at the national or regional levels that goes beyond the silo assessments of the single urban indicators. For example, slum data has now been expanded and new components of informality and inadequate housing are now available. Additionally, aggregate data shows that people who live in slums are also deprived of many other urban services such as access to adequate health care, reliable transport, safe public spaces, and that these residents live in more hazardous environments where municipal solid waste collection services are unavailable.
