3. METHODOLOGY
3.1 The study sites
The study was conducted in six eastern and central African (ECA) countries: Burundi, Ethiopia,
Kenya, Rwanda, Tanzania and Uganda (Figure 1). The study in Ethiopia, Kenya and Uganda was
conducted in 2004/05, while the one in Tanzania, Rwanda and Burundi was conducted in
2005/06. Two to three cities or towns in each of the six countries were selected for the study
based on potato consumption or production (Table 1). Respondents of the cities were stratified
into three homogenous categories based on their status of consumption and processing of
potato chips. These were Hotels, Bars and Restaurants, and Households. In addition to these,
information was collected from supermarkets and local processors. Since the processing and
consumption practices of chips are closely related to different standards and level of wealth,
hotels were further stratified into Five, Three, and One-star Hotels, while Bars and Restaurants
were stratified into High and low Class categories. Households were stratified into High and Low
Income groups.

When selecting the required samples of all the categories, a city or town was divided into
different segments to make sure that every part of the city or town was included in the study. A
total sample size of 225 Hotels, 317 Bars and Restaurants, and 948 household consumers and six
chips processing companies were selected for the study (Table 2).
