Income/Expenditure/Household Survey [hh/ies]
The 66th round (July 2009-June 2010) of NSS is earmarked for survey on "Household Consumer Expenditure" (Schedule 1.0) and "Employment and Unemployment" (Schedule 10). During this round, the following schedules of enquiry were canvassed:
- Schedule 0.0 : list of households
- Schedule 1.0 : consumer expenditure (Type 1 and Type 2)
Type 1 = Uniform and Mixed Reference Period
Type 2 = Modified Mixed Reference Period - Schedule 10 : employment and unemployment
The survey on "household consumer expenditure" and "employment and unemployment" is the eighth quinquennial survey in the series, the last one being conducted in the 61st round (2004-2005) of NSS.
The programme of quinquennial surveys on consumer expenditure and employment & unemployment has been adopted by the National Sample Survey Organisation (NSSO) since 1972-73. Under the programme, the survey on consumer expenditure provides a time series of household consumer expenditure data, which is the prime source of statistical indicators of level of living, social consumption and well-being, and the inequalities thereof. Apart from the quinquennial series (QS), there also exists an "annual series", comprising consumer expenditure surveys conducted in the intervening periods between QS rounds - starting from the 42nd round (July 1986 - June 1987) and using a smaller sample.
The last survey - the seventh - of the quinquennial series was conducted during the 61st round (July 2004 - June 2005). The 66th round is the eighth and was conducted during July 2009 - June 2010.
Household consumer expenditure (HCE) during a specified period, called the reference period, may be defined as the total of the following:
(a) expenditure incurred by households on consumption goods and services during the reference period
(b) imputed value of goods and services produced as outputs of household (proprietary or partnership) enterprises owned by households and used by their members themselves during the reference period
(c) imputed value of goods and services received by households as remuneration in kind during the reference period
(d) imputed value of goods and services received by households through social transfers in kind received from government units or non-profit institutions serving households (NPISHs) and used by households during the reference period.
Reference period and schedule type:
The reference period is the period of time to which the information collected relates. In NSS surveys, the reference period often varies from item to item. Data collected with different reference periods are known to exhibit certain systematic differences. In this round, two schedule types have been drawn up to study these differences in detail. Sample households will be divided into two sets - Schedule Type 1 will be canvassed in one set and Schedule Type 2 in the other. The reference periods to be used for different groups of consumption items are given below, separately for each schedule type.

Sampling
SAMPLE DESIGN
Outline of sample design:
A stratified multi-stage design has been adopted for the 66th 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. In addition, two non-UFS towns of Leh and Kargil of Jammu & Kashmir are also treated as FSUs 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 mean Panchayat wards for Kerala) constitutes the sampling frame. For the urban sector, the list of latest available UFS blocks is considered as the sampling frame. For non-UFS towns, frame consists of the individual towns (only two towns, viz., Leh & Kargil constitute this 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, wherever 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:
There is no sub-stratification in the urban sector. However, to net adequate number of child workers, for all rural strata, each stratum has been divided into 2 sub-strata as follows:
sub-stratum 1: all villages with proportion of child workers (p) >2P (where P is the average
proportion of child workers for the sate/ UT as per Census 2001)
sub-stratum 2: remaining villages
Total sample size (FSUs):
12784 FSUs for central sample and 15132 FSUs for state sample have been allocated at all-India level. Further, data of 24 state sample FSUs of Leh and Kargil districts of J & K surveyed by DES, J & K will be included in the central 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 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 is allocated between two sectors in proportion to population as per census 2001 with double 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. A minimum of 16 FSUs (to the extent possible) is allocated to each state/ UT separately for rural and urban areas. Further the State level allocations for both rural and urban have been adjusted marginally in a few cases to ensure that each stratum/ sub-stratum gets a minimum allocation of 4 FSUs.
Allocation to strata/ sub-strata:
Within each sector of a State/ UT, the respective sample size is allocated to the different strata/ sub-strata in proportion to the population as per census 2001. Allocations at stratum/ sub-stratum level are adjusted to multiples of 4 with a minimum sample size of 4 and 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 urban sector, from each stratum FSUs have been selected by using Simple Random Sampling Without Replacement (SRSWOR). Both rural and urban samples have been drawn in the form of two independent sub-samples.

Survey instrument
Schedule 1.0 consists of several blocks to obtain detailed information on the consumption expenditure and other particulars of the sample household.
It has been decided that two types of Schedule 1.0 viz. Schedule Type 1 and Schedule Type 2 will be canvassed in this round. Schedule Type 1 is similar to Schedule 1.0 of NSS 61st round. Schedule Type 2 has different reference period (7 days) for some items of food, pan, tobacco and intoxicants as compared to 30 days' reference period for these items in Schedule Type 1.
Schedule Type 1 uses the same reference period system as used in the 61st and 50th round consumer expenditure surveys (where there was only one schedule type). Schedule Type 1 requires that for certain items (Group I items), the same household should report data for two reference periods - "Last 30 days" and "Last 365 days".
Schedule Type 2 has the same reference periods as Schedule Type 2 (Sch.1.0) of NSS 60th round. For Group I items, the reference period used in Schedule Type 2 is "Last 365 days".
As in the 60th round, items of food, pan, tobacco and intoxicants (Food-plus category) are split into 2 blocks instead of being placed in a single block.
- The first block (Block 5.1) consists of the item groups cereals, pulses, milk and milk products, sugar and salt (the "F1" category). This block has a reference period of 30 days in both Schedule Type 1 and Schedule Type 2.
- Block 5.2 consists of the other items of food, along with pan, tobacco and intoxicants (the item category "F2+"). This block is assigned a reference period of "Last 30 days" in Schedule Type 1 and a reference period of "Last 7 days" in Schedule Type 2.
Thus Schedule Type 1, like Schedule 1.0 of NSS 61st round, uses the "Last 30 days" reference period for all items of food, and for pan, tobacco and intoxicants.
Schedule 1.0 consists of several blocks to obtain detailed information on the consumption expenditure and other particulars of the sample household.
WHAT IS NEW IN THE SCHEDULE (compared to the 61st/64th round)
- There are two schedule types. Schedule Type 1 is similar to the 61st round schedule. It uses, for some blocks, a double reference period - "last 30 days" and "last 365 days". Schedule Type 2 uses different reference periods of 7, 30 and 365 days for different items. For any particular block, it uses only one reference period.
- Unlike the 61st round schedule (Block 3), there is no question on possession of ration card or on ration card type.
- Unlike the 61st round (Block 3), there is no question on food assistance schemes of the Government from which the household has benefited.
- Block 3 will have a question on use of the internet by household members during the last 30 days.
- In both schedule types, the food-plus item category (food, pan, tobacco & intoxicants) has been split into 2 blocks: Block 5.1 and Block 5.2. For Block 5.1 (cereals, pulses, milk & milk products, sugar and salt), both schedule types use a 30-day reference period. For the remaining food groups, and for pan, tobacco and intoxicants, Schedule Type 1 uses "last 30 days" and Schedule Type 2 uses "last 7 days".
- Foodgrains such as chira, khoi, etc., if reported as obtained from home-produced paddy, may be recorded as consumption out of home produce against chira, khoi, etc., instead of against "rice".
- In Block 5.2, the items "supari", "lime", "katha", and "other ingredients for pan" have been merged to form a single item (312) "ingredients for pan (gm)".
- "Cornflakes", "soyabean", "sunflower/soyabean oil" and "rice bran oil" have been dropped from the list of food items.
- In Block 5.2, item 334, the description "foreign liquor or refined liquor" has been replaced by "foreign/ refined liquor or wine".
- All second-hand purchases of books and journals (and magazines) will be recorded against a separate item (401) in Block 9.
- A new item (406) for "educational CD" has been introduced in the block on education and institutional medical care (Block 9).
- In Block 9, the item (404) "stationery, photocopying charges" has replaced the old item "stationery".
- No information on insurance premium paid will be collected in the schedule.
- In Block 10, there is only one item (420) for medicine. In the 64th round, medicine in Block 10 was split into five items.
- In Block 10, the item (436) "VCD/DVD hire (incl. instrument)" has replaced the item "video cassette/VCR/VCP hire".
- "Telephone charges: mobile" (item 488) in Block 10 will be an unstarred item, that is, actual expenditure incurred during the last 30 days will be recorded. "Telephone charges: landline" (item 487) will remain a starred item, i.e., entry = amount last paid divided by no. of months for which paid.
- The item "tape recorder, CD player" has been dropped from Block 11. Item 562 has been modified slightly to "VCR/VCD/DVD player".
- The item (622) "PC/laptop/other peripherals incl. software" has replaced the old item "personal computer" (Block 11).
- Schedule Type 2 has a block (Block 13) on "Perception of household regarding sufficiency of food".
