Growth settlement refers to the increase or expansion of the place or areas where people live and engage in different economic activities. There was the rapid growth of settlement in Europe after the industrial revolution. The growth of settlement of a given place is always dynamic as it changes time after time due to the different factors. The following are the factors which influence the growth of settlement;-
(a) Provision of social services, People migrate from their original places and live near areas where social services are easily available to them. Example of social services are health centres, schools, electricity and water supply.
(b) Climate condition, People settle in good climatic areas. Rainfall and temperature have a great influence from human settlement. Areas that receive abundant rainfall and favourable temperature attract more people. This is because people are able to engage in both subsistence and commercial farming such areas are Kilimanjaro, Mbeya, Ruvuma and Iringa region where there is abundant rainfall.
(c) Relief; It is a strong factor influencing settlement. Gentle slopes are ideal areas for building houses as they are well drained. Steep stops are usually uninhabited because they have thin soils which inhibit growth of crops and pasture.
(d) Vegetation cover; Vegetation is the total plants cover over an area. Thick vegetation discourages establishment of settlement. Dense forest such as Congo of central Africa and Amazon, in South America are not accessible. They may also be habitants for dangerous wild animals and disease carrying vectors.
(e) Political factor; Political factor has great influence on settlement establishment. A settlement may be located in a certain area because of political reasons for example in 1967 the government of Tanzania introduced ujamaa village where by people were settled in villages.
(f) Economic factor; People establish settlement in places which offer economic opportunities. Migration from rural to urban centres is mainly due to prospects for employment and trading opportunities. Mining activities also leads to the establishments of settlements for example development of Mwadui towns was the results of Mwadui Diamond mines.
(g) Cultural factors; Some areas may be productive but due to some cultural beliefs people may be prohibited to establish settlements on such areas. Example mumbanitu forest in Njombe.
(h) Historical factors; Prior to the division of Africa some communities moved in various directions and settled in their present homelands. Those movements were caused by various factors mainly wars for example Mfecane war in South Africa.
