The income distribution appears to be highly skewed in the SIZ area. While the bottom half
(Deciles 1 to 5) of the actors have 15.4 percent of the total income, the top half (Deciles 6 to 10)
of the actors accounted for as much as 84.5 percent of the total income. The proportion of
decile1 to decile10 is as high as 1:29.
The Gini coefficient, measuring income inequality, for the SIZ area as a whole is estimated as
0.52. As was evident from previous section, the Gini coefficients for individual products are
estimated in the range of 0.40 to 0.53. One can mention, in this context, findings from a study
conducted by BIDS. It was found that in the coastal districts the Gini coefficients vary from 0.19
to 0.36. In no cases, Gini coefficients for any of the coastal districts are higher than or close to
that in the SIZ area. In fact, the coefficients in the SIZ estimate much higher, indicating that so
far the SRF actors’ income is concerned the SIZ area is characterized by severe inequality in
income.

This concluding chapter summarizes and reviews the major findings obtained from the previous
chapters, and relates them to a few major issues. These issues may be crucial to the improvement
