||Education expenses did not come from the Education section where<br>questions were asked for each household member, they come from<br>Form II which had a very detailed section specific for education<br>expenditures, divided into private, public, formal, informal. Unlike the<br>NPS, the structure of the questions was very similar to the other non‐<br>food items.|Education expenses were included in household expenditures but they were collected<br>separately (Section C). Information is collected for each household member over 5 years old<br>with a recall period of 12 months (question 14 in 2008/09, question 28 in 2010/11 and<br>2011/13). Total expenses were calculated by the numerator by adding up individual expenses.<br>Notice that these expenses included some clothing (uniforms) and footwear (shoes).|
||Health expenses did not come from the Health section where<br>questions were asked for each household member. There was a<br>separate section with 15 questions for health expenditures. Unlike the<br>NPS, the structure of the questions was very similar to the other non‐<br>food items.|Health expenditures were included in household total expenditures but they were collected<br>separately. The NPS collected information for each household member over 12 years and old<br>(Section D). Some questions referred to the past four weeks, some to the past 12 months<br>(question 13 onwards) but they seemed properly harmonized in the do files. Health<br>expenditures included expenses related to visits to the health practitioner, health treatments,<br>hospitalization and medications.|
||There is a section for vehicle and a separate section for public<br>transport expenses.|Transport expenses included: Public transport (7 days recall), “petrol or diesel”, “motor vehicle<br>service, repair, or parts”, “bicycle service, repair, or parts” (30 days recall).|
||Communications included telephone landlines, mobile phones,<br>personal computers, satellite decoders.|Communication expenses had a 30‐day recall period (Section L). They included: “cellphone<br>vouchers” and “phone, internet and postal services”.|
