Micro, small, and medium manufacturing enterprises (MSMEs) offer good examples of firm clustering and incipient entry points for industrial development in Tanzania. This study analyses the growth of cluster-based, micro and small furniture-manufacturing firms located in the Keko, Buguruni-Malapa, and Mbezi Beach kwa Komba industrial clusters. The results of quantitative growth indicators show that on average the furniture manufacturing firms in the studied clusters grew, and real payments to the firm owners and workers grew as well.
