RIA ICT Access Survey 2011-2012 - Africa

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

Research ICT Africa (RIA) is a non-profit, public interest, research entity which undertakes research on how information and communication technologies are being accessed and used in African countries. The aim is to measure the impact on lifestyles and livelihoods of people and households and to understand how informal businesses can prosper through the use of ICTs. This research can facilitate informed policy-making for improved access, use and application of ICT for social development and economic growth. RIA collects both supply-side and demand-side data. On the demand-side nationally representative surveys are conducted on ICT use and demand in African countries. This Survey delivers nationally representative indicators on household, individual and small business level. The survey uses national census sampling frames in co-operation with National Statistical Offices to deliver crucial data in a cost effective way.This survey dataset consists of data collected in thirteen African countries in 2011-2012.

Geographic coverage
---------------------------

The surveys had national coverage. Survey countries included Botswana, Cameroon, Ethiopia, Ghana, Kenya, Mozambique, Namibia, Nigeria, Rwanda, South Africa, Tanzania, Uganda, and Tunisia.

Analysis unit

This survey is nationally representative on household, individual and small business level.

Kind of data
---------------------------

Sample survey data

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

The random sampling was performed in four steps for households and businesses, and five steps for individuals.
• Step 1: The national census sample frames was split into urban and rural Enumerator areas (EAs).
• Step 2: EAs were sampled for each stratum using probability proportional to size (PPS).
• Step 3: For each EA two listings were compiled, one for households and one for businesses. The listings serve as sample frame for the simple random sections.
• Step 4: 24 Households and 10 businesses were sampled using simple random sample for each selected EA.
• Step 5: From all household members 15 years or older or visitors staying the night at the house one was randomly selected based on simple random sampling.

样本调查数据

抽样程序
---------------------------
针对家庭和企业，随机抽样分为四个步骤，针对个人则为五个步骤。
• 第1步：国家人口普查样本框架被划分为城市和农村的普查员区域（EAs）。
• 第2步：使用大小成比例的概率抽样（PPS）对每个层级进行EAs抽样。
• 第3步：为每个EA编制两个清单，一个用于家庭，一个用于企业。清单作为简单随机抽样段的抽样框架。
• 第4步：在每个选定的EA中，使用简单随机抽样方法，各抽取24户家庭和10家企业。
• 第5步：从所有15岁及以上的家庭成员或留宿的访客中，根据简单随机抽样方法随机选择一人。
