Hungry Cities Partnership Survey, Windhoek 2016-2019 - Namibia

Abstract
---------------------------

This study covers Windhoek, one of four African cities surved between 2013 and 2019 by the African Center for Cities. The African Center for cities is based at the University of Cape Town and is a partner of the Hungry Cities Partnership (HCP).

The HCP studies include household data on food insecurity, household food purchasing dynamics, nutritional discounting taking place in households, foods consumed and multidimensional measures of poverty. The household data is complimented with household member data and food retailer (vendor) data, including infomation on vendor employees.

The Hungry Cities Partnership is an international network of cities and city-based partner organizations which focuses on the relationships between rapid urbanization, informality, inclusive growth and urban food systems in the Global South.

Sample survey data

Sampling procedure
---------------------------

Household survey: A two-stage sampling procedure was used for the household survey. According to the documention, 35 PSUs were selected from the 2011 census master frame, with selection proportionate to size. This is different to the other cities, where the number of households selected (second stage) was according to relative size. Households were selected from within these PSUs in the second stage using systematic sampling.

Vendor: As of yet DataFirst has not received documentation that corresponds to the vendor data. Users can try browsing the reports published on the hungry cities partnership website for extra information.

Mode of data collection
---------------------------

Face-to-face [f2f]

Research instrument
---------------------------

There are two questionnaires per city, a household questionnaire and a vendor questionnaire. The household questionnaire has a subsection for household members (persons), and the vendor quesitonnaire has a subsection for employees. Answers to these subsections are supplied in separete datafiles, which can be matched to (merged with) the questoinnaire as necessary.

Cleaning operations
---------------------------

Household: The question numbering in the Windhoek data was out of position compared to the other cities and the questionnaire. This was due to some questions (20 and 21) being dropped and an extra question being asked (q17, the five-year version). This was fixed in data cleaning, so that the question numbers again correspond to the questionnaire as well as the other three cities.

Person: The person question number was also out in Windhoek, and was again corrected in the data preparation phase. Users can request records of data preparation and sytax files for more information.

Vendor: The question numbering in the Windhoek data is different. Rather than using letters for subquestions (1a, 1b, 1c) it uses decimals (1.1, 1.2, 1.3). Variables were named to match this using underscores instead of decimal points as well as lettes where these were necessary to avoid too many decimal places. The food questions were also asked differentely in Windhoek, vendors could specify the foods they sell, rather then answer "yes" or "no" to a list of foods.

Employee: Like the vendor data, the employee question numbering does not match the previous cities. The employee data came with the vendor data in Windhoek, but was separated out to match the other cities.

Data appraisal
---------------------------

Household: Questions 20 and 21 are missing from the Windhoek data and it appears they were not asked. Sometimes the "please specify" answer that should go with the selection of "other" is missing despite "other" being given as an answer. In the transfers section, question 10.d about travel time is missing from the data.

Vendor: The Windhoek questionnaire only allows users to enter "missing", not "refused" or "do not know".

本研究涵盖温得和克，这是非洲四座城市之一，由开普敦大学非洲城市中心在2013至2019年间进行调查。非洲城市中心位于开普敦大学，并与饥饿城市伙伴关系（HCP）合作。HCP的研究包括关于食物不安全、家庭食品购买动态、家庭内部发生的营养折价、所消费的食品以及贫困的多维度测量的家庭数据。家庭数据得到了家庭成员数据和食品零售商（摊贩）数据的补充，包括关于摊贩员工的信息。饥饿城市伙伴关系是一个国际城市及其基于城市的合作伙伴组织网络，专注于全球南方快速城市化、非正式性、包容性增长与城市食品系统之间的关系。

样本调查数据
抽样程序
---------------------------
家庭调查：家庭调查采用两阶段抽样程序。根据文件记录，从2011年人口普查主框架中选择了35个抽样单元（PSU），其选择比例与规模成比例。这与其他城市不同，在其他城市，所选择的户数（第二阶段）是根据相对规模来确定的。在第二阶段，从这些PSU中选择家庭，采用系统抽样。
摊贩：截至目前，DataFirst尚未收到与摊贩数据相对应的文件。用户可以尝试浏览饥饿城市伙伴关系网站上发布的报告以获取更多信息。

研究工具
---------------------------
每个城市有两个问卷，一个是家庭问卷，另一个是摊贩问卷。家庭问卷有一个关于家庭成员（个人）的子部分，摊贩问卷有一个关于员工的子部分。这些子部分的答案分别提供在单独的数据文件中，根据需要可以与问卷匹配（合并）。
数据清理操作
---------------------------
家庭：温得和克数据中的问题编号与其他城市和问卷不符，这是由于某些问题（20和21）被删除，并额外提出了一个问题（q17，五年版本）。这在数据清理中得到了纠正，因此问题编号再次与问卷以及其他三个城市相匹配。
个人：个人的问题编号在温得和克也存在，并在数据准备阶段得到了纠正。用户可以要求获取数据准备记录和语法文件以获取更多信息。
摊贩：温得和克数据中的问题编号不同。它不是使用字母为子问题（1a、1b、1c）编号，而是使用小数（1.1、1.2、1.3）。变量被命名为匹配此编号，使用下划线代替小数点，并在必要时使用字母，以避免过多的小数位数。温得和克的食品问题也被不同地提出，摊贩可以指定他们销售的食品，而不是对食品列表回答“是”或“否”。
员工：与摊贩数据一样，员工的编号也不符合之前的城市。员工数据与温得和克的摊贩数据一起提供，但被分开以匹配其他城市。
数据评估
---------------------------
家庭：温得和克数据中缺少问题20和21，似乎这些问题没有被问及。有时，与“其他”选择应伴随的“请指定”答案缺失，尽管已给出“其他”作为答案。在转移部分，关于旅行时间的问题10.d在数据中缺失。
摊贩：温得和克问卷仅允许用户输入“缺失”，而不是“拒绝”或“不知道”。
