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

Sample Design

Outline of sample design

A stratified multi-stage design has been adopted for the 60th round survey. The first stage units (FSU) will be the 1991 census villages in the rural sector and Urban Frame Survey (UFS) blocks in the urban sector. The ultimate stage units (USU) will be households in both the sectors. In case of large villages/blocks requiring hamlet-group (hg)/sub-block (sb) formation, one intermediate stage will be the selection of two hgs/sbs from each FSU.

Sampling Frame for First Stage Units

For the rural sector, the list of Census 1991 villages (panchayat wards for Kerala) and Census 1981 villages for J & K will constitute the sampling frame. For the urban sector, the list of latest available Urban Frame Survey (UFS) blocks will be considered as the sampling frame.

Stratification

Rural sector: Two special strata will be formed at the State/ UT level, viz.
Stratum 1: all FSUs with population between 0 to 50 and
Stratum 2: FSUs with population more than 15,000.

Special stratum 1 will be formed if at least 50 such FSUs are found in a State/UT. Similarly, special stratum 2 will be formed if at least 4 such FSUs are found in a State/UT. Otherwise, such FSUs will be merged with the general strata.
From FSUs other than those covered under special strata 1 and 2, general strata will be formed and its numbering will start from 3. Each district of a State/UT will normally be treated as a separate stratum. However, if the census rural population of the district is greater than or equal to 2.5 million as per population census 2001 or 2 million as per population census 1991, the district will be split into two or more strata, by grouping contiguous tehsils to form strata. However, in Gujarat, some districts are not wholly included in an NSS region. In such cases, the part of the district falling in an NSS region will constitute a separate stratum.

Urban sector: In the urban sector, strata will be formed within each NSS region on the basis of size class of towns as per Population Census 2001. The stratum numbers and their composition (within each region) are given below.
stratum 1 : all towns with population less than 50,000
stratum 2 : all towns with population 50,000 or more but less than 2 lakhs
stratum 3 : all towns with population 2 lakhs or more but less than 10 lakhs
stratum 4, 5, 6,...: each town with population 10 lakhs or more

The stratum numbers will remain as above even if, in some regions, some of the strata are not formed.

Total sample size (FSUs)

7612 FSUs have been allocated at all-India level on the basis of investigator strength in different States/UTs for central sample and 8260 for state sample.

Allocation of total sample to States and UTs

The total number of sample FSUs is allocated to the States and UTs in proportion to provisional population as per Census 2001 subject to the availability of investigators ensuring more or less uniform work-load.

Allocation of State/UT level sample to rural and urban sectors

State/UT level sample is allocated between two sectors in proportion to provisional population as per Census 2001 with 1.5 weightage to urban sector subject to the restriction that urban sample size for bigger states like Maharashtra, Tamil Nadu etc. should not exceed the rural sample size. Earlier practice of giving double weightage to urban sector has been modified considering the fact that there has been considerable growth in urban population. A minimum of 8 FSUs will be allocated to each state/UT separately for rural and urban areas.

Allocation to strata:

Within each sector of a State/UT, the respective sample size will be allocated to the different strata in proportion to the stratum population as per census 2001. Allocations at stratum level will be adjusted to a multiple of 4 with a minimum sample size of 4.

Selection of FSUs

FSUs will be selected with Probability Proportional to Size With Replacement (PPSWR), size being the population as per Population Census 1991 in all the strata for rural sector except for stratum 1. In stratum 1 of rural sector and in all the strata of urban sector, selection will be done using Simple Random Sampling Without Replacement (SRSWOR). Within each stratum, samples will be drawn in the form of two independent sub-samples in both the rural and urban sectors.

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

Proper identification of the FSU boundaries: The first task of the field investigators is to ascertain the exact boundaries of the sample FSU as per its identification particulars given in the sample list. For urban samples, the boundaries of each Urban Frame Survey (UFS) block may be identified by referring to the map corresponding to the frame code specified in the sample list (even though map of the block for a latter period of the UFS might be available).

Criterion for hamlet-group/sub-block formation: After identification of the FSU, it is to be determined whether listing will be done in the whole sample FSU or not. In case the population of the selected village or block is found to be 1200 or more, it will be divided into a suitable number (say, D) of „hamlet-groups? in the rural sector and „sub-blocks? in the urban sector as stated below.
less than 1200 (no hamlet-groups/sub-blocks) 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, Nagaland and Poonch, Rajouri, Udhampur, Doda districts of Jammu and Kashmir and Idukki district of Kerala, the number of hamlet-groups will be formed as follows.
approximate present population of the sample village no. of hgs to be formed
less than 600 (no hamlet-groups) 1
600 to 899 3
900 to 1199 4
1200 to 1499 5
.………..and so on

Two hamlet-groups/sub-blocks will be selected from a large village/UFS block wherever hamlet-groups/sub-blocks have been formed, by SRSWOR. Listing and selection of the households will be done independently in the two selected hamlet-groups/sub-blocks.

Formation of hamlet-groups/sub-blocks: In case hamlet-groups/sub-blocks are to be formed in the sample FSU, the same should be done by more or less equalizing population (details are in Chapter Two). Note that while doing so, it is to be ensured that the hamlet-groups/sub-blocks formed are clearly identifiable in terms of physical landmarks.

Listing of households: Having determined the hamlet-groups/sub-blocks, i.e. area(s) to be considered for listing, the next step is to list all the households (including those found to be temporarily locked after ascertaining the temporariness of locking of households through local enquiry). The hamlet-group/sub-block with sample hg/sb number 1 will be listed first and that with sample hg/sb number 2 will be listed next.

Formation of Second Stage Strata and allocation of households for Schedule 25.0

In each selected village/block/hamlet-group/sub-block, four second stage strata (SSS) will be formed as given below.
SSS 1: households with at least one member hospitalised during last 365 days
SSS 2: from the remaining households, households having at least one child of age below 5 years
SSS 3: from the remaining households, households with at least one member of age 60 years or above
SSS 4: other households

Selection of households for Schedules 1.0, 10 and 25.0

From each SSS the sample households for all the schedules will be selected by SRSWOR. If a household is selected for more than one schedule only one schedule will be canvassed in that household in the priority order of Schedule 1.0, Schedule 10 and Schedule 25.0 and in that case the household will be replaced for the other schedule. If a household is selected for Schedule 1.0 it will not be selected for Schedule 10 or Schedule 25.0. Similarly, if a household is not selected for Schedule 1.0 but selected for Schedule 10 it will not be selected for Schedule 25.0. However, for the household, selected from SSS1 of Schedule 25.0, the Schedule 25.0 will be canvassed even if the household is selected for other schedules.

Sampling deviation
---------------------------

Shortfall of households to be compensated

For schedule 1.0, 10 and 25.0, shortfall of households available in the frame of any SSS will be compensated from the same SSS of the other hg/sb or from the other SSS of the same or other hg/sb where additional household(s) are available. The procedure is as follows:
Step 1: Allocate the required number of households to each SSS wherever possible and identify the SSS having shortfall.
Step 2: In case of hg/sb formation, compensate from the same SSS of the other hg/sb if available. Otherwise, go to Step 3.
Step 3: Find the SSS where additional households are available following the priority order of SSS 1, SSS 2, SSS 3 & SSS 4 and compensate.

If there is hg/sb formation, for each SSS as per priority order, compensation may be made from the hg/sb where shortfall occurs, failing which from other hg/sb and so on.
Similarly, if shortfall is in SSS 3 of hg/sb 1 for sch. 25.0, first try to compensate from SSS3 of hg/sb 2, failing which try from SSS 1 of hg/sb 1, failing which try from SSS 1 of hg/sb 2. If the shortfall still remains then try from SSS 2 of hg/sb 1, failing which try from SSS 2 of hg/sb 2 and so on.

For schedules 1.0 and 10, the procedure will be same except that choice will be limited to SSS 1 and SSS 2 only.

For example, if shortfall is in SSS 2 of hg/sb 2 for sch. 1.0 or sch. 10, first try to compensate from SSS 2 of hg/sb 1, failing which try from SSS 1 of hg/sb 2. If the shortfall still remains then try from SSS 1 of hg/sb 1.

The resulting number of households (h) for each SSS will be entered at the top of relevant column(s) of block 5 and also in col.(6) against the relevant SSS × (hg/sb) of block 6.

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60轮调查采用了分层多阶段设计。第一阶段单元（FSU）将是农村部门的1991年人口普查村庄和城市部门的城市框架调查（UFS）区块。最终阶段单元（USU）将是两个部门的家庭。在需要形成村庄群组（hg）/子区块（sb）的大型村庄/区块的情况下，每个FSU将选择两个hg/sb作为中间阶段。
第一阶段单元的抽样框架
对于农村部门，1991年人口普查村庄名单（喀拉拉邦的潘查亚特辖区）和1981年人口普查村庄名单（查谟和克什米尔邦）将构成抽样框架。对于城市部门，最新可用的城市框架调查（UFS）区块名单将被考虑作为抽样框架。
分层
农村部门：在州/特区级别将形成两个特殊层，即
层1：所有人口在0至50之间的FSU
层2：人口超过15,000的FSU
如果在某个州/特区中至少发现50个此类FSU，则将形成特殊层1。同样，如果在某个州/特区中至少发现4个此类FSU，则将形成特殊层2。否则，此类FSU将与一般层合并。
从除特殊层1和2之外的FSU中，将形成一般层，其编号从3开始。每个州/特区的每个区通常被视为一个单独的层。但是，如果根据2001年人口普查的农村人口普查，该区的农村人口超过或等于2.5百万，或者根据1991年人口普查的农村人口超过或等于2百万，则该区将分为两个或更多层，通过将相邻的 tahsil 组合成层来实现。然而，在古吉拉特邦，一些区并未完全包含在 NSS 区域内。在这种情况下，属于 NSS 区域的部分将构成一个单独的层。
城市部门：在城市部门，将根据2001年人口普查的城镇规模形成每个 NSS 区域内的层。以下给出了层编号及其组成（在每个区域内部）。
层1：所有人口少于50,000的城镇
层2：人口50,000或更多但少于20万的城镇
层3：人口20万或更多但少于100万的城镇
层4、5、6等：人口100万或更多的每个城镇
即使在某些区域中某些层未形成，层编号也将保持不变。
全印度层面的总样本量（FSU）
根据不同州/特区的调查员实力，在中央样本中分配了7612个FSU，在州样本中分配了8260个。
将总样本量分配给州和特区
将总样本量分配给州和特区时，将按照2001年人口普查的临时人口比例分配，同时确保调查员的工作量大致均匀。
将州/特区层面的样本分配给农村和城市部门
州/特区层面的样本将在两个部门之间按2001年人口普查的临时人口比例分配，城市部门的权重为1.5，但受制于大州如马哈拉施特拉邦、 Tamil Nadu 等等的城市样本量不应超过农村样本量的限制。考虑到城市人口有相当大的增长，已经修改了以前对城市部门给予双倍权重的做法。每个州/特区分别将至少分配8个FSU用于农村和城市地区。
层的分配
在州/特区的每个部门中，将根据根据2001年人口普查的层人口比例将相应的样本量分配给不同的层。层级别的分配将调整为4的倍数，最小样本量为4。
FSU的选择
将使用与规模成比例的概率有放回抽样（PPSWR）选择FSU，规模为农村部门的除层1之外所有层的人口，根据1991年人口普查。
农村部门层1和城市部门的各层将使用简单随机抽样无放回（SRSWOR）进行选择。在每个层内，样本将以两种独立子样本的形式在农村和城市部门中抽取。
村庄群组/子区块/家庭的选拔 - 重要步骤
正确识别FSU边界：现场调查员的首要任务是确定样本FSU的精确边界，该边界根据样本名单中给出的识别细节给出。对于城市样本，可以通过参考样本名单中指定的框架代码对应的地图来识别每个城市框架调查（UFS）区块的边界（即使UFS后期的区块地图可能可用）。
村庄群组/子区块形成的标准：在识别FSU后，需要确定是否在全部样本FSU中进行编制。如果发现所选村庄或区块的人口为1200人或更多，则将根据以下所述将其划分为适量的“村庄群组”（在农村部门）和“子区块”（在城市部门）。
少于1200人（无村庄群组/子区块）
1200至1799人
1800至2399人
2400至2999人
3000至3599人
……以此类推
对于喜马偕尔邦、锡金、纳加兰邦和查谟和克什米尔邦的 Poona、Rajouri、Udhampur、Doda 区以及喀拉拉邦的伊杜基区，村庄群组的形成如下。
样本村庄的近似当前人口
要形成的村庄群组数量
少于600人（无村庄群组）
600至899人
900至1199人
1200至1499人
……以此类推
在形成村庄群组/子区块的情况下，从形成村庄群组/子区块的较大村庄/UFS区块中，通过SRSWOR选择两个村庄群组/子区块。在两个选定的村庄群组/子区块中独立进行家庭编制和选择。
形成村庄群组/子区块：如果需要在样本FSU中形成村庄群组/子区块，则应通过大致均衡人口（详情见第二章）的方式来进行。请注意，在这样做的时候，应确保形成的村庄群组/子区块在物理地标方面可以清楚地识别。
家庭编制：确定村庄群组/子区块后，即确定要考虑编制的区域，下一步是列出所有家庭（包括通过当地调查确定锁定为暂时性的家庭）。首先列出样本hg/sb编号为1的村庄群组/子区块，然后列出样本hg/sb编号为2的村庄群组/子区块。
形成第二阶段层和为25.0号日程分配家庭
在每个选定的村庄/区块/村庄群组/子区块中，将形成以下四个第二阶段层（SSS）。
SSS 1：过去365天内至少有一名成员住院的家庭
SSS 2：从剩余的家庭中，至少有一名5岁以下儿童的家庭
SSS 3：从剩余的家庭中，至少有一名60岁或以上的成员的家庭
SSS 4：其他家庭
为1.0号、10号和25.0号日程选择家庭
从每个SSS中，将通过SRSWOR选择所有日程的样本家庭。如果一个家庭被选为多个日程，则在该家庭中仅调查优先级顺序为日程1.0、日程10和日程25.0的日程，在这种情况下，该家庭将替换为其他日程。如果一个家庭被选为日程1.0，则不会选为日程10或日程25.0。同样，如果一个家庭未被选为日程1.0但选为日程10，则不会选为日程25.0。然而，对于从日程25.0的SSS 1中选出的家庭，即使该家庭被选为其他日程，也将调查日程25.0。
抽样偏差
---------------------------
需要补偿的家庭短缺
对于1.0号、10号和25.0号日程，任何SSS框架中可用的家庭短缺将从其他hg/sb的同一SSS或从同一或其他hg/sb的其他SSS中补偿，其中还有额外的家庭可用。程序如下：
步骤1：在可能的情况下，将所需数量的家庭分配给每个SSS，并确定短缺的SSS。
步骤2：在形成hg/sb的情况下，如果可用，则从其他hg/sb的同一SSS中补偿。否则，进入步骤3。
步骤3：按照SSS 1、SSS 2、SSS 3 & SSS 4的优先级顺序找到有额外家庭可用的SSS并进行补偿。
如果形成hg/sb，对于每个SSS按照优先级顺序，如果短缺发生，可以从短缺发生的hg/sb中进行补偿，如果不行，则从其他hg/sb，依此类推。
同样，如果hg/sb 1的SSS 3中存在短缺，对于sch. 25.0，首先尝试从hg/sb 2的SSS 3中进行补偿，如果不行，则尝试从hg/sb 1的SSS 1中进行补偿，如果不行，则尝试从hg/sb 2的SSS 1中进行补偿。如果短缺仍然存在，则尝试从hg/sb 1的SSS 2中进行补偿，如果不行，则尝试从hg/sb 2的SSS 2，依此类推。
对于1.0号和10号日程，程序将与上述相同，但选择将仅限于SSS 1和SSS 2。
例如，如果hg/sb 2的SSS 2中存在短缺，对于sch. 1.0或sch. 10，首先尝试从hg/sb 1的SSS 2中进行补偿，如果不行，则尝试从hg/sb 2的SSS 1中进行补偿。如果短缺仍然存在，则尝试从hg/sb 1的SSS 1中进行补偿。
每个SSS的结果家庭数量（h）将记录在块5的相关列顶部，并在块6的相关SSS × (hg/sb)列的（6）栏中。
