The United Republic of Tanzania scores low on the 2016 Human Development Index positioning the country at 151 out of 188 countries. Despite recent economic growth and immense governmental efforts, poverty remains a pressing issue for the nation, with income levels among the lowest in Africa. Today, half of all Tanzanians live below the poverty line and approximately one-third live in extreme poverty. More than a third of the households earn less than $1 a day, while 20% of the total population lives below the food poverty line. Tanzania has a population of 55.5 million spread across 945,087 sq km. Swahili and English are the most spoken languages.
