Abstract

This report presents population projections for the period 2003 to 2025 for Tanga Region as well as its districts. The projections were made using a Cohort Component Method (Spectrum System), whereby three components responsible for population change, namely: mortality, fertility and migration were projected separately as well as HIV/AIDS prevalence. The projected components were then applied to 2002 midyear base population in order to come up with the desired projections from 2003 to 2025. The report gives mortality, fertility, migration and HIV/AIDS assumptions, and shows Tanga’s demographic and socio-economic future trends. The results include the estimated population by sex in single years and five-year age groups as well as some demographic indicators. The results show that population growth for the period 2003 to 2025 shows a decrease in growth rates. The projections show that population growth rate will decrease from 2.2 percent in 2003 (with a population of 1,672,581) to 1.9 percent in 2025 (with a population of 2,639,366). Sex Ratio at birth is projected to increase slightly from 94 male per 100 females in 2003 to 95 male per 100 females in 2025. Mortality estimates show that Infant Mortality Rate (IMR) is expected to decline for both sexes from 101 deaths per 1,000 live births in 2003 to 52 deaths per 1,000 live births in 2025. Under Five Mortality Rate (U5MR) for both sexes will also decline from 168 deaths per 1,000 live births in 2003 to 79 deaths per 1,000 live births in the year 2025. The mortality projected estimates further show that the life expectancy at birth for males is lower compared to that of females, which is expected. Life expectancy at birth for Tanga will increase from 51 years in 2003 to 59 years in 2025 for both sexes. For male population, life expectancy at birth will increase from 51 years in year 2003 to 55 years in 2025, while for female population, the life expectancy at birth will increase from 51 years in 2003 to 63 years in 2025. On fertility, TFR will decline from 4.8 children per woman in 2003 to 3.4 children per woman in 2025.
