Abstract
OBJECTIVE: To examine the extent to which the regional and neighborhood distribution of HIV in Tanzania is caused by the differential distribution of individual correlates and risk factors. METHODS: Nationally representative, cross-sectional data on 12,522 women and men aged 15-49 years from the 2003-2004 Tanzanian AIDS Indicator Survey. Three-level multilevel binary logistic regression models were specified to estimate the relative contribution of regions and neighborhoods to the variation in HIV seroprevalence. RESULTS: Spatial distribution of individual correlates (and risk factors) of HIV do not explain the neighborhood and regional variation in HIV seroprevalence. Neighborhoods and regions accounted for approximately 14 and 6% of the total variation in HIV. HIV prevalence ranged from 1.8% (Kigoma) to 6.7% (Iringa) even after adjusting for the compositional make-up of these regions. An inverse association was observed between log odds of being HIV positive and neighborhood poverty [odds ratio (OR) 0.24, 95% confidence interval (CI) 0.09-0.61] and regional poverty (OR 0.97, 95% CI 0.95-0.99). CONCLUSION: Our study provides evidence for independent contextual variations in HIV, above and beyond that which can be ascribed to geographical variations in individual-level correlates and risk factors. We emphasize the need to adopt both a group-based and a place-based approach, as opposed to the dominant high-risk group approach, for understanding the epidemiology of HIV as well as for developing HIV intervention activities.

Publication The Household Enterprise Sector in Tanzania : Why It Matters and Who Cares(2011-11-01)The household enterprise sector has a significant role in the Tanzanian economy. It employs a larger share of the urban labor force than wage employment, and is increasingly seen as an alternative to agriculture as a source of additional income for rural and urban households. The sector is uniquely placed within the informal sector, where it represents both conditions of informal employment and informal enterprise. This paper presents a case study on Tanzania using a mixed approach by combining both quantitative and qualitative analysis to examine the important role of household enterprises in the labor force of Tanzania, and to identify key factors that influence their productivity. Household enterprise owners are similar to typical labor force participants although primary education appears to be the minimum qualification for household enterprise operators to be successful. Access to location matters -- good, secure location in a marketplace or industrial cluster raises earnings - and access to transport and electricity is found to have a significant effect on earnings as well. In large urban areas, the biggest constraint faced by household enterprises is the lack of access to secure workspace to run the small business. Although lack of credit is a problem across all enterprises in Tanzania, household enterprises are more vulnerable because they are largely left out of the financial sector either as savers or borrowers. Although HEs are part of the livelihood strategies of over half of households in Tanzania, they are ignored in the current development policy frameworks, which emphasize formalization, not productivity. Tanzania has a large number of programs and projects for informal enterprises, but there is no set of policies and program interventions targeted at the household enterprise sector. This gap exacerbates the vulnerability of household enterprises, and reduces their productivity.Publication Socioeconomic Status and HIV Seroprevalence in Tanzania : A Counterintuitive Relationship(2008)OBJECTIVE: To examine the relationship between multiple dimensions of socioeconomic status (SES) and HIV seroprevalence in Tanzania. METHODS: Using a large nationally representative sample of 7515 sexually active adults drawn from the 2003-04 Tanzania HIV/AIDS Indicator Survey, we analysed the relationship between multiple SES measures and HIV seroprevalence using weighted logistic regression models. RESULTS: In adjusted models, individuals in the highest quintile of standard of living had increased odds ratio (OR) of being HIV-positive (male: OR 2.38, 95% CI 1.17-4.82; female: OR 3.74, 95% CI 2.16-6.49). Occupational status was differentially associated with HIV in men and women; women in professional jobs had higher OR of being HIV-positive (OR 1.54, 95% CI 1.02-2.38), whereas unemployed men had higher risk of being HIV-positive (OR 3.49, 95% CI 1.43-8.58). No marked association was found between increasing education and HIV seroprevalence for men (P = 0.83) and women (P = 0.87). CONCLUSION: Contrary to the prevailing perception that low SES individuals tend to be more vulnerable to HIV-infection, we found a positive association between standard of living and HIV-infection. Strategies aimed at reducing HIV-infection needs to be cognizant of the complex social heterogeneity in the patterns of HIV-infection.Publication Urban Labor Markets in Sub-Saharan Africa(Washington, DC: World Bank and Agence Française de Développement, 2013-06-07)The population of Sub-Saharan Africa stood at 854 million in 2010. Annual population growth averaged 2.5 percent, with a relatively high sustained fertility rate, fostered by the fact that two-thirds of the population is under 25. The region has the highest proportion of poor people in the world, with 47.5 percent of its population living on less than $1.25 a day, as measured in terms of purchasing power parity in 2008. It is also the only region in which the number of poor is still rising. This book contributes to knowledge on the functioning of urban labor markets in Sub-Saharan Africa by investigating following questions: which individuals lack access to employment or are employed beneath their capacities; does education improve working conditions?; what opportunities does the labor market offer to climb the social ladder?; is the lack of good-quality jobs for adults and the poverty it implies one of the reasons for the prevalence of child labor?; do women and ethnic minorities have the same access to the labor market as everyone else?; how does the formal sector live alongside the informal sector?; what role does migration play in the functioning of labor markets?;and are there traits common to all urban labor markets in Africa, or is each country different? This book attempts to answer these questions by studying 11 cities in 10 countries (table O.1). Comparative studies are often based on disparate measurement instruments, which risk marring the validity of the findings. This study is based on a set of perfectly comparable surveys. The study also covers a number of topics (migration, child labor, job satisfaction, discrimination, and work after retirement) in addition to the topics covered by Lachaud (unemployment, access to employment and mobility, segmentation, labor supply, and poverty). This book is divided in five parts. The first is comparative analysis of urban labor markets in Sub-Saharan Africa; second is job quality and labor market conditions in Sub-Saharan Africa; third is dimensions of labor market inequalities; fourth is the key coping mechanisms and private responses; and fifth is moving forward.Publication Youth in Africa's Labor Market(Washington, DC : World Bank, 2008)Youth and Africa have received increased attention in recent policy discussions and World Bank work, as articulated in the Africa action plan and the World Development Report 2007: development and the next generation. The Africa action plan offers a framework to support critical policy and public action led by African countries to achieve well-defined goals, such as the Millennium Development Goals (MDGs). The World Development report's main message is that the time has never been better to invest in young people living in developing countries. It offers a three pillar policy framework for investing in and preserving the human capital of the next generation. Both frameworks respond to the desire to find solutions to Africa's development challenges and to prepare for and benefit from the next generation of workers, parents, and leaders. This report examines the challenges Africa's youth face in their transition to working life and proposes policies for meeting these challenges. It presents evidence from case studies of 4 countries - Burkina Faso, Ethiopia, Tanzania, and Uganda and from household data on 13 countries. The four case studies include a stocktaking of existing policies and programs to address youth employment and labor markets. The overarching message of the report is the call to further invest in the human capital of youth in Sub-Saharan Africa to take advantage of the large youth cohorts there. Youth in Africa leave school too early and enter the labor market unprepared, limiting their contribution to economic growth and increasing their vulnerability to poverty and economic hardship.Publication The Labor Market, Education and Armed Conflict in Tajikistan(2011-07-01)Shortly following its independence in 1991, Tajikistan suffered a violent civil war. This study explores the effect of this conflict on education and labor market outcomes for men and women. The results are based on the data from the 2003 and 2007 Tajik Living Standards Measurement Surveys that were separated from the 1992-1998 Tajik civil war by five and nine years, respectively. The regression analysis that controls for the cohort and regional-level exposure points toward a persistent and lasting gap in the educational attainment by women who were of school age during the war and lived in the more conflict-affected regions as compared with women the same age who lived in the lesser affected regions and also to the older generation. These empirical results support the anecdotal and observational evidence about the decline in female educational attainment in Tajikistan. Interestingly, this group of young women is more likely to hold a job as compared with the rest of the analytical sample. Conditional on being employed, men and women in the more conflict-affected areas do not receive wages that are significantly different from wages received by men and women in the lesser affected areas.
