The mean ages were higher in the city areas that were designated consumption areas and they
varied from 32 in Addis Ababa and Awassa (Ethiopia) to 59 in Mombassa (Kenya). The maximum
age of respondents also had a similar trend with Gisenyi-Rwanda being lowest (51) and
Mombassa-Kenya highest (85).
4.3.2 Family sizes of households
The average family size of the sample households among the high and low income groups of the
respondents in Burundi, Ethiopia, Kenya, Rwanda and Uganda is seven and ranges from a mean
of 2 to 14 (Table 6). The average family sizes of high income households are higher than those of
the low income households. The size of family has a role to play in adopting technologies that
require human labor. For instance, chips processing technologies require labor for washing
potatoes, peeling, chips making and frying. Moreover, family size affects the demand for
products. Large family size, especially children and youths in a household in urban areas, might
imply more demand for chips and since the high income groups have larger households, this
creates a higher demand for foods associated with the rich such as chips.

4.4. Source and qualities of processing potatoes
4.4.1 Sources of potatoes for chips processing
Each country had specific varieties preferred for chips processing (Table 7) which, however, was
affected by availability. In Ethiopia, 72% of the overall sample hotels purchase potatoes directly
from wholesale vegetable markets, while 28% of the hotels get potatoes directly supplied to
