The World Happiness Report, produced by United Nations Sustainable Development Solutions, ranks 156 countries, and Denmark has been one of the happiest since the report’s inception in 2012. Happiness is measured through positive affect, negative affect, and life evaluations (which include GDP, social support, healthy life expectancy, freedom to make life choices, generosity, and absence of corruption). Social support is constructed through the built environment through proximity of buildings and services that typically are not placed together. For example, this addiction clinic (building to the right) is found next to a popular restaurant on a main street. Bringing together different kinds of people can break down stereotypes and create a sense of community.
