| description |
This study carries out a thorough
investigation of the potential sources of mismatch in
poverty and inequality levels and trends between the
Tanzania National Panel Survey and Household Budget Survey.
The main findings of the study include the following. First,
the difference in poverty levels between the Household
Budget Survey and the National Panel Survey is essentially
explained by the differences in the methods of estimating
the poverty line. Second, the discrepancy in poverty trends
can be mainly attributed to the difference in inter-year
temporal price deflators, and, to a lesser extent, spatial
price deflators. The use of the consumer price index for
adjusting consumption variation across years would show a
decline in poverty during the past five years for the
Household Budget Survey and the National Panel Survey.
Third, despite noticeable differences in the methods of
household consumption data collection, the Household Budget
Survey and National Panel Survey show close mean household
consumption levels in the last rounds, when using the
consumer price index to adjust for inter-year price
variations. Mean household consumption levels in the
Household Budget Survey 2011/12 and National Panel Survey
2010/11 are comparable, and the mean consumption level in
the National Panel Survey 2012/13 is around 10 percent
higher. The difference is driven by higher levels of
aggregate and food consumption by the better-off groups in
the National Panel Survey. Fourth, the mismatch in
inequality trends and pro-poor growth patterns between the
two surveys could not be resolved and is a subject for
further analysis. |
