National Sample Survey 2011-2012 (68th round) - Schedule 10 - Employment and Unemployment - India

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

Objective of the survey on employment and unemployment:

The basic objective of the employment-unemployment surveys of NSSO is to get estimates of the employment and unemployment characteristics at national and State level. The statistical indicators on labour market are required for planning, policy and decision making at various levels, both within government and outside. Some of the important uses of these indicators include use by the Planning Commission in evolving employment strategy, use by National Accounts Division in estimating gross domestic product using sector wise workforce participation, and use by various researchers to analyse the condition of the labour market. In this context, it may be mentioned that data collected in NSS employment-unemployment surveys was widely used by the National Commission for Enterprises in the Unorganised Sector (NCEUS), 2009. In NSS 68th round, information on various facets of employment and unemployment will be collected in Schedule 10 (Employment and Unemployment) from all the members of the selected households.

The critical issues in the context of labour force enquiries pertain to defining the labour force and measuring participation of labour force in different economic activities. The activity participation of the people is not only dynamic but also multidimensional; it varies with region, age, education, gender, industry and occupational category. These aspects of the labour force will be captured in detail in the present survey on employment and unemployment. Major types of information that will be collected in this round relate to activity status, industry, occupation and earning from employment for the employees along with education particulars, etc. Besides, the survey will also provide insight into the informal sector and informal employment. Information will be collected from the workers about the type of enterprises in which they were engaged and conditions of employment for the employees. Using the data collected from employment and unemployment surveys, indicators will be generated on labour force participation rate, worker population ratio, unemployment rates, employment in the informal sector, informal employment, wages of employees, etc.

Description:

The survey on employment and unemployment is the prime source of estimates of various parameters of labour force and activity participation of the population. The first quinquennial survey on employment - unemployment, carried out by the NSSO in the 27th round (September 1972 - October 1973), made a marked departure from the earlier employment surveys of NSSO in procedure and content. The concepts and procedures followed in this survey were primarily based on the recommendations of the 'Expert Committee on Unemployment Estimates' (1970). Since then, the seven successive quinquennial surveys conducted in the 32nd, 38th, 43rd, 50th, 55th, 61st and 66th rounds have, more or less, followed an identical approach in the measurement of employment and unemployment. The basic approach (in all these seven quinquennial surveys) had been the collection of data to generate the estimates of employment and unemployment according to the 'usual status' based on a reference period of one year, the 'current weekly status' based on a reference period of one week, and the 'current daily status' based on each day of the seven days preceding the date of survey. In order to reveal the multi-dimensional aspects of the employment-unemployment situation in India, information on several correlates were also gathered in these surveys. Sets of probing questions on some of these aspects had also been one of the basic features of these surveys. In NSS 68th round (July 2011- June 2012), detailed information on employment-unemployment was collected in the same way as was done in the last quinquennial survey, i.e., in NSS 66th round.

A Working Group was set up for the purpose of finalising the survey methodology and schedules of enquiry of the 68th round. Considering all the aspects of current data demand and usefulness of the survey results, the Group has suggested a few improvisations, additions and deletions in the content of the schedule of enquiry for the present survey. The major changes made in the schedule for employment and unemployment survey vis-à-vis the previous quinquennial survey (NSS 66th round) are given below:

a) Block 3:
1) In NSS 66th round survey, along with the information on 'whether the household has NREG job card', information was collected on 'whether got work in NREG works during the last 365 days', 'number of days worked' and 'mode of payment'. In NSS 68th round for rural households, information on Mahatma Gandhi National Rural Employment Guarantee (MGNREG) works was collected on the following:
i. whether the household has MGNREG job card
ii. number of MGNREG job cards issued to the household
iii. whether any member of the household has any bank/post office account
Information on the last two items (viz., ii & iii) will be collected from the households which have got MGNREG job card.
2) Household type codes and procedure for determination of household type codes in rural areas have been modified.

b) Block 3.1: In this block information on indebtedness of rural labour households was collected in NSS 66th round. This Block was not canvassed in NSS 68th round.

c) Block 4:
i. Instead of collecting information on 'whether currently registered with employment exchange' for persons of age 15-45 years as was done in NSS 66th round, information was collected for the same age group on 'whether currently registered with any placement agency'.
ii. In NSS 66th round, for vocational training, detailed information was collected on 'duration of training', 'source from which degree/diploma/certificate received' and 'whether the vocational training was ever helpful in getting a job'. In NSS 68th round, collection of information on vocational training was restricted only to 'whether receiving/received any vocational training' and 'field of training'.
iii. For persons of age 18 years and above in rural households with MGNREG job card, information was collected on 'whether registered in any MGNREG job card' and, for those who were registered in any MGNREG job card 'whether worked in MGNREG work during last 365 days'. Such information was not collected in NSS 66th round.

d) Block 5.1/5.2:
i. Information on 'seeking or available or suitable for the type of occupation' which was collected in NSS 66th round in Block 5.1 from the non-workers of age below 75 years, was not collected.
ii. The probing questions to the self-employed persons in the usual status (Block 5.1/5.2) to identify Home Based Workers have been deleted.

e) Block 5.3:
i. In this block, for those who were unemployed on all the 7 days of the week, information was also collected on 'duration of present spell of unemployment'. In NSS 66th round, this question was placed in Block 6. Except retaining this item in Block 5.3, Block 6 of NSS 66th round on follow-up questions for persons unemployed on all the 7 days of the week has been deleted.

f) Block 6 (Block 7.1/7.2 of NSS 66th round):
i. Block 7.1 and Block 7.2 have been restructured by deleting some of the items and a new block (Block 6) has been formed in NSS 68th round.
ii. Questions on remunerativeness of the earning from self-employment which were asked in NSS 66th round in Block 7.1 to the self-employed persons in principal status and/or subsidiary status have been deleted. These were, 'do you regard the current earning from self-employment as remunerative?' and 'what amount per month would you regard as remunerative?'.
iii. Information was collected in NSS 66th round in Block 7.2 on some aspects of labour mobility, such as, whether changed establishment, status, industry, occupation during the period of last two years. Information on these items was not collected in NSS 68th round.
iv. The three items of Block 7.2 of NSS 66th round which have been retained in NSS 68th round are placed in Block 6. These are:
1. Is there any union/association in your activity?
2. Whether a member of union/association
3. Nature of employment

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

The survey will cover the whole of the Indian Union except (i) interior villages of Nagaland situated beyond five kilometres of the bus route and (ii) villages in Andaman and Nicobar Islands which remain inaccessible throughout the year.

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

Sample survey data [ssd]

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

Sample design

Outline of sample design:
A stratified multi-stage design has been adopted for the 68th round survey. The first stage units (FSU) are the 2001 census villages (Panchayat wards in case of Kerala) in the rural sector and Urban Frame Survey (UFS) blocks in the urban sector. The ultimate stage units (USU) are households in both the sectors. In case of large FSUs, one intermediate stage of sampling is the selection of two hamlet-groups (hgs)/ sub-blocks (sbs) from each rural/ urban FSU.

Sampling Frame for First Stage Units:
For the rural sector, the list of 2001 census villages (henceforth the term 'village' would include also Panchayat wards for Kerala) constitutes the sampling frame. For the urban sector, the list of UFS blocks (2007-12) is considered as the sampling frame.

Stratification:
Within each district of a State/ UT, generally speaking, two basic strata have been formed: i) rural stratum comprising of all rural areas of the district and (ii) urban stratum comprising of all the urban areas of the district. However, within the urban areas of a district, if there are one or more towns with population 10 lakhs or more as per population census 2001 in a district, each of them forms a separate basic stratum and the remaining urban areas of the district are considered as another basic stratum.

Sub-stratification:
Rural sector r: If 'r' be the sample size allocated for a rural stratum, the number of sub-strata formed would be 'r/4'. The villages within a district as per frame were first arranged in ascending order of population. Then sub-strata 1 to 'r/4' have been demarcated in such a way that each sub-stratum comprised a group of villages of the arranged frame and have more or less equal population.
Urban sector: If 'u' be the sample size for an urban stratum, 'u/4' number of sub-strata have been formed. In case u/4 is more than 1, implying formation of 2 or more sub-strata, this is done by first arranging the towns in ascending order of total number of households in the town as per UFS phase 2007-12 and then arranging the IV units of each town and blocks within each IV unit in ascending order of their numbers. From this arranged frame of UFS blocks of all the towns/million plus city of a stratum, 'u/4' number of sub- strata formed in such a way that each sub-stratum has more or less equal number of households as per UFS 2007-12.

Total sample size (FSUs):
12784 FSUs have been allocated for the central sample at all-India level and 14772 FSUs have been allocated for state sample.

Allocation of total sample to States and UTs:
The total number of sample FSUs has allocated to the States and UTs in proportion to population as per census 2001 subject to a minimum sample allocation to each State/ UT. While doing so, the resource availability in terms of number of field investigators has been kept in view.

Allocation of State/ UT level sample to rural and urban sectors:
State/ UT level sample size has been allocated between two sectors in proportion to population as per census 2001 with double weightage to urban sector. However, if such weighted allocation resulted in too high sample size for the urban sector, the allocation for bigger states like Maharashtra, Tamil Nadu, etc. was restricted to that of the rural sector. A minimum of 16 FSUs (minimum 8 each for rural and urban sector separately) is allocated to each state/ UT.

Allocation to strata/ sub-strata:
Within each sector of a State/ UT, the respective sample size has been allocated to the different strata/ sub-strata in proportion to the population as per census 2001. Allocations at stratum level are adjusted to multiples of 4 with a minimum sample size of 4. Allocation for each sub-stratum is 4. Equal number of samples has been allocated among the four sub-rounds.

Selection of FSUs:
For the rural sector, from each stratum/ sub-stratum, required number of sample villages has been selected by probability proportional to size with replacement (PPSWR), size being the population of the village as per Census 2001.
For the urban sector, UFS 2007-12 phase has been used for all towns and cities and FSUs have been selected from each stratum/sub-stratum by using Simple Random Sampling Without Replacement (SRSWOR).
Both rural and urban samples are to be drawn in the form of two independent sub-samples and equal number of samples have been allocated among the four sub rounds.

Selection of hamlet-groups/ sub-blocks - important steps

Criterion for hamlet-group/ sub-block formation:
After identification of the boundaries of the FSU, it is first determined whether listing is to be done in the whole sample FSU or not. In case the population of the selected FSU is found to be 1200 or more, it has to be divided into a suitable number (say, D) of 'hamlet-groups' in the rural sector and 'sub-blocks' in the urban sector by more or less equalising the population as stated below.
less than 1200 -> 1
1200 to 1799 -> 3
1800 to 2399 -> 4
2400 to 2999 -> 5
3000 to 3599 -> 6
..and so on

For rural areas of Himachal Pradesh, Sikkim, Uttarakhand (except four districts Dehradun (P), Nainital (P), Hardwar and Udham Singh Nagar), Poonch, Rajouri, Udhampur, Doda, Leh (Ladakh), Kargil districts of Jammu and Kashmir and Idukki district of Kerala, the number of hamlet-groups are formed as follows:
less than 600 -> 1
600 to 899 -> 3
900 to 1199 -> 4
1200 to 1499 -> 5
..and so on

Formation and selection of hamlet-groups/ sub-blocks:
In case hamlet-groups/ sub-blocks are formed in the sample FSU, the same is done by more or less equalizing population. Two hamlet-groups (hg)/ sub-blocks (sb) are selected from a large FSU wherever hamlet-groups/ sub-blocks have been formed in the following manner - one hg/ sb with maximum percentage share of population is always selected and termed as hg/ sb 1; one more hg/ sb is selected from the remaining hg's/ sb's by simple random sampling (SRS) and termed as hg/ sb 2. Listing and selection of the households is done independently in the two selected hamlet-groups/ sub-blocks. The FSUs without hg/ sb formation are treated as sample hg/ sb number 1. It is to be noted that if more than one hg/ sb have same maximum percentage share of population, the one among them which is listed first in block 4.2 of schedule 0.0 is treated as hg/ sb 1.

Formation of second stage strata and allocation of households
Two cut-off points 'A' and 'B' (in Rs.) have been determined from NSS 66th round data for each NSS state-region for urban areas in such a way that top 10% of the population have MPCE more than 'B' and bottom 30% of the population have MPCE less than A.
For both Schedule 1.0 and Schedule 10, households listed in the selected FSU/ hamlet-group/ sub-block are stratified into three second stage strata (SSS).

Selection of households:
From each SSS the sample households for each of the schedules are selected by SRSWOR. If a household is selected for more than one schedule, only one schedule is canvassed in that household in the priority order of Schedule 1.0 (Type 1), Schedule 1.0 (Type 2) and Schedule 10 and in that case the household would be replaced for the other schedule. If a household is selected for Schedule 1.0 (Type 1) it is not selected for Schedule 1.0 (Type 2) or Schedule 10. Similarly, if a household is not selected for Schedule 1.0 (Type 1) but selected for Schedule 1.0 (Type 2) it is not selected for Schedule 10.

摘要
--------------------------------------

就业与失业调查的目标：

国家统计调查组织（NSSO）的就业与失业调查的基本目标是为全国及各州级水平上的就业和失业特征提供估计。劳动市场统计指标对于各级政府内外规划、政策制定和决策至关重要。这些指标的一些重要用途包括：规划委员会在制定就业战略时使用、国民经济核算司使用行业劳动力参与度估计国内生产总值，以及各研究人员分析劳动市场状况。在此背景下，值得一提的是，2009年国家非正规部门企业委员会（NCEUS）广泛使用了NSS就业与失业调查收集的数据。在NSS第68次调查轮次中，将通过第10号计划（就业与失业）从所选家庭的全体成员中收集关于就业和失业各方面信息。

劳动人口调查的临界问题涉及定义劳动人口以及衡量劳动人口在不同经济活动中的参与度。人们的活动参与不仅动态多变，而且多维多样；它受地区、年龄、教育、性别、行业和职业类别的影响。本调查将对劳动力的这些方面进行详细捕捉。本次调查将收集的主要信息类型包括活动状态、行业、职业以及员工就业收入等，以及教育等相关信息。此外，调查还将深入了解非正规部门和就业情况。将收集工人关于他们参与的企业类型以及员工就业条件的信息。利用从就业与失业调查中收集的数据，将生成关于劳动人口参与率、工人人口比率、失业率、非正规部门就业、非正规就业、员工工资等指标。

描述：

就业与失业调查是估算劳动力及人口活动参与度各项参数的主要数据来源。国家统计调查组织（NSSO）在1972年9月至1973年10月的第27次轮次中进行的首次五年期就业-失业调查，在程序和内容上与NSSO先前进行的就业调查有显著不同。本调查采用的概念和程序主要基于“失业估计专家委员会”（1970年）的建议。自那时起，第32次、第38次、第43次、第50次、第55次、第61次和第66次轮次中进行的连续七个五年期调查，在就业和失业的测量上，或多或少地遵循了相同的方法。所有这七个五年期调查的基本方法都是收集数据，根据一年的参考期“通常状态”估计就业和失业，根据一周的参考期“当前每周状态”估计，以及根据调查日期前七天的每一天“当前每日状态”估计。为了揭示印度就业-失业状况的多维度特征，这些调查还收集了关于几个相关因素的信息。关于这些方面的调查问题集也是这些调查的基本特征之一。在NSS第68次调查轮次（2011年7月至2012年6月），就业-失业的详细信息收集方式与上一次五年期调查（NSS第66次轮次）相同。

为最终确定第68次轮次的调查方法和调查问卷，成立了一个工作组。考虑到当前数据需求以及调查结果的实用性，该小组建议对本次调查问卷的内容进行一些改进、增加和删除。以下列出了与上一轮五年期调查（NSS第66次轮次）相比，就业和失业调查问卷中做出的主要更改：

a) 第3部分：
1) 在NSS第66次轮次调查中，除了收集关于“家庭是否拥有NREG工作卡”的信息外，还收集了关于“在过去365天内是否在NREG工作中获得工作”、“工作天数”和“支付方式”的信息。在NSS第68次轮次中，对于农村家庭，关于马哈特玛甘地国家农村就业保障（MGNREG）工作的信息如下：
i. 家庭是否拥有MGNREG工作卡
ii. 发给家庭的MGNREG工作卡数量
iii. 家庭任何成员是否有银行/邮局账户
将从拥有MGNREG工作卡的家庭收集关于最后两项（即第ii项和第iii项）的信息。
2) 已修改了家庭类型代码及其在农村地区的确定程序。

b) 第3.1部分：在NSS第66次轮次调查中，在第3.1部分收集了关于农村劳动家庭负债的信息。在NSS第68次轮次中，没有进行此调查。

c) 第4部分：
i. 与NSS第66次轮次调查中收集关于15-45岁年龄段“是否目前在就业交易所注册”的信息不同，对于同一年龄段，在第68次轮次调查中收集了关于“是否目前在任何安置机构注册”的信息。
ii. 在NSS第66次轮次调查中，对于职业培训，收集了关于“培训持续时间”、“学位/文凭/证书来源”以及“职业培训是否曾经有助于找工作”的详细信息。在第68次轮次调查中，仅收集了关于职业培训的信息，包括“是否接受/接受过任何职业培训”和“培训领域”。
iii. 对于拥有MGNREG工作卡的农村家庭中18岁及以上的人员，收集了关于“是否在任何MGNREG工作卡中注册”的信息，以及对于已注册的人员，“在过去365天内是否在MGNREG工作中工作”。在NSS第66次轮次调查中没有收集此类信息。

d) 第5.1/5.2部分：
i. 在NSS第66次轮次调查中，在第5.1部分收集了关于“寻求或可供或适合某种职业”的信息，这是从75岁以下的非工人中收集的，在第68次轮次调查中没有收集此类信息。
ii. 删除了关于通常状态下自我雇佣人员的问题，以识别家庭工作工人。

e) 第5.3部分：
i. 在此部分，对于一周中所有七天都失业的人，还收集了关于“目前失业期的持续时间”的信息。在NSS第66次轮次调查中，此问题放在第6部分。除了保留第5.3部分中的此项外，NSS第66次轮次关于一周中所有七天都失业的人的后续问题（即第7.1和第7.2部分）已被删除。

f) 第6部分（NSS第66次轮次的第7.1/7.2部分）：
i. 第7.1和第7.2部分已被重组，删除了一些条目，并在NSS第68次轮次中形成了一个新的部分（第6部分）。
ii. 在NSS第66次轮次中，在第7.1部分向主要状态和/或辅助状态下的自我雇佣人员询问关于自雇佣收入收益性的问题已被删除。这些问题是：“您是否认为当前的自雇佣收入是有收益的？”以及“您认为每月多少收入是有收益的？”。
iii. 在NSS第66次轮次中，在第7.2部分收集了关于劳动力流动性的一些方面的信息，例如，在过去两年中是否改变了企业、状态、行业、职业。在NSS第68次轮次中没有收集这些信息。
iv. NSS第66次轮次的第7.2部分的三个条目在NSS第68次轮次中得以保留，并被放在第6部分。这些是：
1. 您的活动中是否有任何工会/协会？
2. 您是否是工会/协会的成员？
3. 就业性质

地理覆盖范围
--------------------------------------

调查将涵盖整个印度联邦，但以下地区除外：（i）纳加兰邦内距公交车路线五公里以外的内陆村庄，以及（ii）全年无法到达的安达曼和尼科巴群岛的村庄。

数据类型
--------------------------------------

样本调查数据 [ssd]

抽样程序
--------------------------------------

样本设计

样本设计概述：
第68次调查采用了分层多阶段设计。第一阶段单位（FSU）是农村部门的2001年人口普查村庄（在喀拉拉邦情况下为村议会区）和城市框架调查（UFS）区块。最终阶段单位（USU）是两个部门的家庭。对于大型FSU，一个中间抽样阶段是从每个农村/城市FSU中选择两个村庄组（hgs）/子区块（sbs）。

第一阶段单位抽样框架：
对于农村部门，2001年人口普查村庄的名单（因此，“村庄”一词也将包括喀拉拉邦的村议会区）构成了抽样框架。对于城市部门，2007-12年UFS区块的名单被视为抽样框架。

分层：
在各省/自治区/直辖区，一般来说，形成了两个基本层：i)包括该地区所有农村地区的农村层，以及ii)包括该地区所有城市地区的城市层。然而，在一个地区的城市地区内，如果有一个或多个城镇的人口按2001年人口普查超过一百万，那么每个城镇都形成一个单独的基本层，该地区的其余城市地区被视为另一个基本层。

亚分层：
农村部门r：如果“r”是一个农村层的样本量，则形成的亚层数量为“r/4”。根据框架，按人口升序排列的每个区的村庄首先被排列。然后，亚层1到“r/4”被划定为这样的方式，即每个亚层由一组按人口排列的村庄组成，并且人口大致相等。
城市部门：如果“u”是一个城市层的样本量，则形成“u/4”个亚层。如果u/4大于1，这意味着形成2个或更多亚层，这是通过首先按UFS阶段2007-12中城镇的总家庭数量升序排列城镇，然后按每个城镇的IV单位以及每个IV单位内的区块的编号升序排列每个IV单位的IV单位。从所有城镇/百万以上城市层的UFS区块的排列框架中，形成“u/4”个亚层，以这种方式形成每个亚层大致有相同数量的家庭，根据UFS 2007-12。
总样本量（FSU）：
在全国范围内分配了12784个FSU作为中央样本，为各省/自治区/直辖区分配了14772个FSU。

各省/自治区/直辖市样本分配：
将总样本量分配给各省/自治区/直辖市的比例与2001年人口普查的人口比例相同，但每个省/自治区/直辖市至少分配一个样本。在此过程中，考虑了资源可用性，即调查员数量。

省/自治区/直辖市层面样本到农村和城市部门的分配：
省/自治区/直辖市层面的样本量根据2001年人口普查的人口比例分配给两个部门，城市部门有双倍权重。然而，如果这种加权的分配导致城市部门的样本量过高，则对较大的州，如马哈拉施特拉邦、泰米尔纳德邦等，其分配限制为农村部门的分配。每个省/自治区/直辖市至少分配16个FSU（农村和城市部门各自至少8个）。

层/亚层分配：
在每个省/自治区/直辖区的一个部门内，将相应的样本量按2001年人口普查的人口比例分配给不同的层/亚层。在层级的分配中，将分配调整到4的倍数，最小样本量为4。每个亚层的分配为4。在四个子轮次中，样本数量平均分配。

FSU选择：
对于农村部门，从每个层/亚层中选择所需数量的样本村庄，通过与规模成比例的概率抽样有放回（PPSWR），规模是2001年人口普查的村庄人口。对于城市部门，使用简单随机抽样无放回（SRSWOR）从每个层/亚层中选择FSU。农村和城市样本均以两个独立的子样本的形式抽取，并在四个子轮次中平均分配样本数量。

村庄组/子区块选择 - 重要步骤

村庄组/子区块形成的标准：
在确定FSU的边界后，首先确定是否在整个样本FSU中进行登记。如果发现所选FSU的人口为1200人或更多，则必须将其划分为约D个“村庄组”在 rural 部门和“子区块”在 urban 部门中，以大致平衡以下所述的人口。

小于1200 -> 1
1200至1799 -> 3
1800至2399 -> 4
2400至2999 -> 5
3000至3599 -> 6
...以此类推

对于喜马偕尔邦、锡金、 Uttarakhand（除四个区 Dehradun（P）、Nainital（P）、Hardwar 和 Udham Singh Nagar）、Poonch、Rajouri、Udhampur、Doda、Leh（Ladakh）、Kargil 区的 Jammu 和 Kashmir 以及喀拉拉邦的伊杜基区，村庄组的形成如下：
小于600 -> 1
600至899 -> 3
900至1199 -> 4
1200至1499 -> 5
...以此类推

村庄组/子区块的形成和选择：
如果在样本FSU中形成村庄组/子区块，则通过大致平衡人口进行。在形成村庄组/子区块的情况下，从大型FSU中选择两个村庄组（hg）/子区块（sb），如下所述 - 总人口百分比份额最大的一个村庄组/子区块总是被选中，并称为hg/ sb 1；从剩余的hg's/ sb's中选择一个更多的hg/ sb，通过简单随机抽样（SRS）进行选择，并称为hg/ sb 2。在两个选定的村庄组/子区块中独立进行登记和选择家庭。对于没有形成村庄组/子区块的FSU，被视为样本hg/ sb 1。请注意，如果有多个hg/ sb具有相同的人口百分比份额最大，则首先在0.0计划第4.2部分中列出的是hg/ sb 1。

第二阶段层的形成和家庭分配
从每个NSS州-地区为城市地区确定了两个截止点“A”和“B”（以卢比为单位），以便使得人口前10%的MPCE超过“B”，而人口后30%的MPCE低于“A”。

对于计划1.0和计划10，所选FSU/村庄组/子区块中的家庭按以下方式分层为三个第二阶段层（SSS）。

家庭选择：
从每个SSS中选择样本家庭，为每个计划选择。如果一个家庭被选为多个计划，则在优先顺序为计划1.0（类型1）、计划1.0（类型2）和计划10的情况下，在该家庭中仅 canvassed 一个计划，在这种情况下，该家庭将替换为其他计划。如果一个家庭被选为计划1.0（类型1），则不会选为计划1.0（类型2）或计划10。同样，如果一个家庭未被选为计划1.0（类型1），但被选为计划1.0（类型2），则不会选为计划10。
