Tanzania achieves a Happy Planet Index Score of 30.7 and ranks #133 of all the countries analysed.

Tanzania's HPI score reflects a low life expectancy, very low levels of experienced well-being, and a low ecological footprint.

Tanzania's experienced well-being score is 3.2 out of a possible 10.

This score is very low. It is the lowest of all the countries analysed and considerably below the world average (5.28) and the average of countries in Sub Saharan Africa (4.33)

The data for experienced well-being draws on responses to the ladder of life question in the Gallup World Poll, which was asked to samples of around 1000 individuals aged 15 or over in each of the countries included in the Happy Planet Index.

Tanzania's life expectancy is 58.2 and ranks #123 among the 151 countries analysed.

This is below the average life expectancy of all the countries analysed (69.9), but above the average life expectancy in Sub Saharan Africa (54.8)

The life expectancy figure for each country was taken from the 2011 UNDP Human Development Report and reflects the number of years an infant born in that country could expect to live if prevailing patterns of age-specific mortality rates at the time of birth in the country stay the same throughout the infant’s life.

Tanzania's Ecological Footprint is 1.19 global hectares per capita.

If everyone had the same Ecological Footprint as the average citizen of Tanzania:

  • the world's Ecological Footprint would be 60% lower
  • the world would operate comfortably within sustainable environmental limits

Ecological Footprint is a metric of human demand on nature, used widely by NGOs, the UN and several national governments. It measures the amount of land required to sustain a country’s consumption patterns.

For a majority of the countries (142 of the 151), Ecological Footprint data were obtained from the 2011 Edition of Global Footprint Network National Footprints Accounts. For the nine other countries included (Belize, Comoros, Djibouti, Guyana, Hong Kong, Iceland, Luxembourg, Malta, and Palestine), Ecological Footprint figures were estimated using predictive econometric models.
