Current knowledge on poverty differential in Tanzania Information on consumption based poverty head count estimates are available in the Household Budget Survey reports (2011/12, 2007 and 2000/01 ) Using asset index generated from DHS as proxy for income poverty The best these two can do is to provide regional estimates given their respective sample sizes.

Where are the poor? We have seen differences between Dar es salaam, other urban and rural. Thus it is very likely that there are differences between regions and within regions. Knowledge on these lower level differences is crucial for policy development and planning.

Why Poverty Mapping Geographical variations - Visual aid Subnational data Scarce resource allocation Used for targeting and budgeting by: Policy makers NGO, FBOs and CSOs Development partners
How was poverty mapping done?.. We combine data from the 2011/12 HBS with the 2012 population census. This allows representative poverty estimates at levels below that of the region. Only estimates for Dar es Salaam and rural enumeration areas are provided. The estimates are results of modeling and simulations based on this modeling.
How was poverty mapping done? Stage 0: identify common variables in both survey and census. Stage 1: modeling of per adult equivalent consumption Stage 2: apply equation to the census data Stage 3: use GIS to map the obtained estimates
MODELING AND PREDICTION Stage 1: Data from household budget survey to predict exppc Regression analysis log(exppc) = β 0 + β 1 X 1 + β 2 X 2 + β n X n + U Output β 0 β 1 β 2 β n seβ Stage 2: Data from Census Calculation log(exppc) = β 0 + β 1 X 1 + β 2 X 2 + β n X n Estimated poverty and inequality for regions and districts Source: IFPRI, 2004

Ranking of different indicators
Alternative applications of the small area estimation method Small area estimation can be used in Nutrition mapping, poverty mapping among small economic groups e.g. Children and disabled Disabled heads of household Disabled
Concluding remarks Poorest areas do NOT necessary have the largest number of poor people Not all indicators can be linked to poverty Include a village (EA) module in census The long form of the census should be administered to the whole population
Concluding remarks To better target the poor one should be aware of three things a) Who are the poor b) Where are the poor and c) Why are they poor Poverty mapping have answered the first two questions and more research is needed to answer the third one
