Journal ArticleCrops’ production and marketing in Tanzania are affected by socio- demographic factors. However, such factors have been given little attention. Thus, this study assesses the relationship between socio- demographic factors and maize production and marketing in Ludewa district. The Solow growth model, which guides the study, indicates that among other economic growth determinants, socio-demographic factors are important. A two-stage sampling mechanism was employed to obtain a sample of 427 farmers. In the first stage, study area was purposively selected and in the second stage, farmers were selected through simple random sampling procedures. A semi-structured questionnaire was used to collect data from the sampled farmers. Checklists were used to collect information from focus group discussions and key respondents. Findings from descriptive analysis reveals that age, sex, and education level significantly influence the size of land grown with maize, while the farming experience influences maize output. Furthermore, the results reveal that age, sex, marital status, and education level significantly influenced marketing participation. The study recommends enhancement of socio- demographic factors for high quality human capital resources.
