Currently, the agriculture sector accounts for nearly half of the GDP of the Tanzania economy and employs nearly 80% of the workforce in the country.

Growing in impact and importance, however, is the Tanzania tourism sector, which currently ranks as the second highest foreign exchange earner in the country behind agriculture.

The mineral production of natural resources such as gold, diamonds and tanzanite has also grown significantly in the last decade and currently represents the largest source of economic growth in Tanzania, providing over 3% of the GDP and accounting for half of the exports from Tanzania.

Today, the industrial sector in Tanzania is one of the smallest in Africa and accounts for less than 10% of the Tanzania GDP, however the sector continues to be of considerable importance to the Tanzania economy as it is still one of the most reliable sources of government revenue in terms of import sales as well as for both corporate and income taxes, accounting for over half of the annual government revenue collection.
