Tanzania achieved full self-government on May 1st, 1961 and adopted its constitution on December 9th, 1962. It is a member of the British Commonwealth, the Organization of African Unity and the United Nations. Tanzania is a developing country predominantly dependent upon agriculture. Tanzania's rate of economic development, relative to other African countries, is mid-way between the wealthiest and the poorest. The economic development of Tanzania is analyzed in detail between the years from 1961 to 197. The dual policy of development adopted by the Tanzanian government called for unbalanced growth in both agriculture and industry. To a certain extent that policy was proven successful.
