Household Budget Survey 2011 - Moldova

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

Moldova Household Budget Survey (HBS) 2011 was implemented by the National Bureau of Statistics of the Republic of Moldova (formerly the Department for Statistics and Sociology of the Republic of Moldova).

Information obtained from the Household Budget Survey is used in the calculation of some macroeconomic indicators: final consumption of households, the Consumer Price Index, the informal trade, etc. Each year, the main indicators of income and expenditure and living conditions are presented to various international organizations: International Labor Organization, World Bank, Food and Agriculture Organization of the United Nations, etc.

Data is collected through face-to-face interviews and the households' income and expenditure diary.

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

Sampling methodology for Moldova HBS was re-designed in 2006.

The updated HBS sample was selected using information from the Population Census 2004 and a joint database of electricity consumers in the whole country. 129 Primary Sampling Units (PSU) are now covered by HBS (before 2006, 45 PSUs were surveyed).

A larger number of PSUs improves regional estimates and ensures a representative sample not only for cities, towns and rural areas as did the previous survey, but also at the level of four statistical zones (North, Centre, South, and Chisinau). Moreover, both Chisinau and Balti municipialities are treated as a large primary sampling unit, from where households are selected, whereas before only some districts were included in the sample.

Two-stage probability sample is used to select households.

1) Sampling procedure: 1st stage - sampling with probabilities proportional to size (PPS) in each strata; 2nd stage - simple random sample (SRS) of households in each PSU.

2) Rotation scheme: 1st stage - about 20% of PSUs will be annually replaced; 2nd stage - one half of households will participate in the survey during five consecutive years and the rest of households will be replaced with the new ones.

Updated HBS sampling design does not use substitution in case of non-response.

The main household questionnaire and the household register are used to collect information within the HBS. In addition, the instructions on filling in, the non-answer form, the list of selected households and the letter to the household are used.

摘要
---------------------------
2011年摩尔多瓦家庭预算调查（HBS）由摩尔多瓦共和国国家统计局（原摩尔多瓦共和国统计局和社会学部）实施。
家庭预算调查获得的信息被用于计算一些宏观经济指标：家庭最终消费、消费者价格指数、非正式贸易等。每年，收入和支出以及生活条件的主要指标都会向各种国际组织提交，包括国际劳工组织、世界银行、联合国粮食及农业组织等。
数据通过面对面访谈和家庭的收入与支出日记收集。

抽样程序
---------------------------
摩尔多瓦HBS的抽样方法于2006年进行了重新设计。
更新后的HBS样本是根据2004年人口普查信息和全国电力用户联合数据库选定的。现在，HBS涵盖了129个一级抽样单位（PSU）（在2006年之前，调查了45个PSU）。
PSU数量的增加提高了区域估计的准确性，并确保了不仅对于城市、城镇和农村地区，而且在四个统计区域（北部、中部、南部和基希讷乌）层面上的代表性样本，如前一次调查所做的那样。此外，基希讷乌和Balti市政当局被视为一个大一级抽样单位，从那里选择家庭，而在此之前，只有一些地区被包括在样本中。
采用两阶段概率样本来选择家庭。
1) 抽样程序：第一阶段 - 在每个层中使用规模比例抽样（PPS）；第二阶段 - 在每个PSU中进行简单随机抽样（SRS）。
2) 旋转方案：第一阶段 - 大约20%的PSU将每年更换；第二阶段 - 一半的家庭将在连续五年内参与调查，其余家庭将被新的家庭所取代。
更新后的HBS抽样设计在非响应情况下不使用替代。
