Socioeconomic status (SES) Socioeconomic status (SES) is one of the most important
social determinants of health and disease, thus, a widely
studied construct in the social sciences.
 SES influences the accessibility, affordability, acceptability
and actual utilization of available health facilities
 Socioeconomic status (SES) is a combination of social and
economic variables
Definition
 A composite measure that typically incorporates
economic, social, and work status .
 Economic status is measured by income.
 Social status is measured by education, and
 Work status is measured by occupation.
• Each status is considered an indicator.
• These three indicators are related but do not overlap
SES Scales and health
 Low SES population presenting more commonly with
nutritional deficiency and communicable diseases and
 High SES showing more of obesity and noncommunicable
diseases;
 Access to healthcare with high SES showing a better
access.
Methods for social classification
 Status inequalities between individuals are common,.
 In general, the more complex the society, the more
numerous the layers or strata of social differentiation
Defintion SES Scale
 The position that an individual or family occupies with
reference to the prevailing average standards of cultural
and material possessions, income, and participation in
group activity of the community
Why SES scale?
1. Understand the distribution of population based on SES
2. To develop a uniform system of socioeconomic
classification of the population universally based on the
income with scientific basis
3. Resources are scarce
a. Need to identify the most needy
b. Difficulty in identifying the exact number of people living
below the poverty line (BPL families) in India
International SES scale
 Hollingshead scale, (The Hollingshead Four Factor Index
of Socioeconomic Status is a survey designed to measure
social status of an individual based on four domains:
Marital status, retired/employed status, educational
attainment, and occupational prestige.)
 Mac Arthur scale (Domains: Education, income,
occupational status and wealth)
Standard of Living Index (SLI) scale
 (NFHS - II) had used the Standard of Living Index (SLI) scale
 Contains 11 items viz. house type, source of lighting, toilet
facility, main fuel for cooking, source of drinking water,
separate room for cooking, ownership of the house,
ownership of agricultural land, ownership of irrigated
land, ownership of livestock, ownership of durable goods
 Used for measuring the SES both urban and rural areas
for the entire country

items, the total score is summed up.
 With the help of the key provided in the manual, total
score is interpreteding terms of the class.
Social class
 Above 43 Upper Class (I)
 33-42 Upper Middle Class (II)
 24-32 Middle Class (III)
 13-23 Lower Middle Class (IV)
 Below 13 Lower Class (V)
Merits
 Includes many domains
Limitations
 This scale does not emphasize the income aspect
 Can only be used for rural subjects
 Caste system varies in each state
BG Prasad socioeconomic scale
 Per capita monthly income = Total monthly income of the
family/Total members of family.
The need to update SES scale
 Income ranges in the scale lose their relevance following
the depreciation in the value of the rupee .
 Steady inflation, lower interest rates, and country’s
current account deficits are the main factors contributing
to fall in the value of currency.
 Therefore, it is needed to update the scale regularly for
socioeconomic classification of study populations.
Inflation
Current account deficit
Methods to update SES scale
 Kumar had tried to update Prasad Scale’s income limits
using consumer price index (CPI)
 Kuppuswamy socioeconomic scale was revised with CPI .
 Linking of the scale with price index makes it relevant
and meaningful and also provides a opportunity for
constant updation .
Price index
 A price index (plural: “price indices” or “price indexes”) is
a normalized average (typically a weighted average)
of price relatives for a given class of goods or services in a
given region, during a given interval of time
 Calculating the CPI for a single item
Wholesale price index(1902)
 The change in the average price level of 676 commodities
traded in wholesale market
 Weekly basis availability
Consumer Price Index (CPI)
 Definition: A comprehensive measure used for estimation
of price changes in a basket of goods and services
representative of consumption expenditure in an
economy is called consumer price index
Consumer price index(1970)
 Comprises multiple series classified based on different
economic group
 4 series
CPI UNME (Urban Non-Manual Employee) -20th-CSO
CPI AL (Agricultural Labourer)-20 th
CPI RL (Rural Labourer)-20 th
CPI IW (Industrial Worker)-last day of month
 From February 2011 the CPI (UNME) released by CSO is
replaced as CPI (urban),CPI (rural) and CPI (combined)
 The prices of 85,000 items from 22,000 stores, and
35,000 rental units are added together and averaged.
They are weighted this way:
 Housing: 41.4%, Food and Beverage: 17.4%,
 Transport: 17.0%, Medical Care: 6.9%,
 Other: 6.9%, Apparel: 6.0%,
 Entertainment: 4.4%.
 Taxes (43%) are not included in CPI computation.
 Consumer Price Index is used in calculation of Dearness
Allowancewhich forms an integral part of salary of a
Government Employee.Base year to calculate CPI is
2001=100
 CENTRAL= Avg AICPIN for 12 months-261.4 ×100
261.4
 Kerala = Avg AICPIN for 12 months-239.92 ×100
239.92
Modified BG Prasad socioeconomic
scale
 Modified BG Prasad socioeconomic scale is widely used to
determine the socioeconomic status .
 The BG Prasad scale was formulated in 1961 keeping the
base of Consumer Price Index (CPI) for 1960 as 100
 Mishra, undertook the important task of revision of
family income per month for 1998 using base year
1982=100.Presently the base year has been changed
from 1982 to 2001
 The Consumer Price Index (CPI) for industrial workers (IW)
is used to calculate updated income categories
Updating Prasad’s Scale
 The BG Prasad scale was formulated in 1961Consumer
Price Index (CPI) for 1960 as 100.
 This was revised in 1982 by introducing a linking factor
of 4.93 to convert CPI (1982) from the new base of 100
to the old base CPI (1960).
 Again a need was felt in 2001 to revise the base, which
was done by introducing the linking factor of 4.63.
Formula updated as for January
2017
 CPI [IW]× 4.63× 4.93 ÷ 100.
 [ 274 × 4.63) × 4.93 ÷ 100.
 = 62.5429=62.5

MERITS
 Can assess the socioeconomic status in both rural and
urban areas
 Only income considered
 Per capita family income so includes all earning members
 Can be updated
Limitation
 It is only income-based scale
 No other domains addressed
 Inflation not considered
Kuppuswamy’s socioeconomic
scale
 The most widely used scale for urban population was
devised by Kuppuswamy in 1976.
 Kuppuswamy scale is a composite score of education and
occupation of the head of the family along with monthly
income of the family, which yields a score of 3-29.
 This scale classifies the study populations into high,
middle, and low SES
 To get current income group, a conversion factor
calculated based on current All India Consumer Price
Index (AICPI) is applied
Contents
 Manual
 Two information blanks (one for the person concerned
and second for the father or guardian)
 Score card
• The information is collected in the devised
Information blanks and with the help of
the score card the status score is obtained.
• On the basis of the total score, the
respective class is found out.

Modification in income slabs
 In 1976 the CPI was taken as 296 based on 1960
 In 1982 new CPI base was set at 100 when 1960 based
value became 460 (so multiplying factor 4.6)
 In 2001 CPI base was set at 100 and when 1982 based
valur reached 490 (so multiplying factor 4.9)
 As per 2017 January CPI value is 274 base year 2001

Merits
 Main 3 domains are considered
 Income total family income
Limitations
 Steady inflation and consequent fall in the value of currency
make the economic criteria in the scale less relevant.
 Income part is considered to be the total income of the
family and no consideration is given to size of the family:
 A small family with a particular income will have higher SES
status than a bigger-sized family with similar income.
 There is an overemphasis on income
 Material possessions not considered

Marketing
Research Society of India scoring
 Based on two variables
 Number of “consumer durables” (from a predefined
list)-owned by the family. The list has 11 items,
ranging from ‘electricity connection’ and ‘agricultural
land’-to cars and air conditioners
 Education of chief earner
 The household is categorised into one of the five groups
Class I – Upper;
ClassII – Upper Middle;
Class III – Lower Middle
Class IV – UpperLower
Class V – Lower Lower
Kerala Socio-Economic Status scale
 A. Sukumaran Nair's (1976)
 The general data sheet is divided into 5 sections
 Section one elicits the name, age, caste, religion, locality
of the school, place of residence etc.
 The second part calls for information regarding the level
of education of parents, siblings and other occupants of
the family
 Section three elicits the details of occupation of the
members of the family
 The last part (fifth) contains the information regarding the
school marks.
 Here, the highest income given was 2501/- and above and
lowest was 300. But in now a day's even a coolie earns
750-800 per day
DEMERITS
 The education and the lifestyle of people are totally
improved. So the application of this scale in this changed
social condition of Kerala is in question
Summary
 SES is a predictor of health status
 Socioeconomic status (SES) is a combination of social and
economic variables
 SES Scales help to develop a uniform system of socioeconomic
classification of the population universally based on the
income with scientific basis
 Udai Pareek and G. Trivedi scale, Kuppuswamy scale 1962, B G
Prasad classification are some Indian SES scales .
 Steady inflation, lower interest rates, and country’s current
account deficits are the main factors contributing to fall in the
value of currency, so, it is needed to update the scale regularly
for socioeconomic classification of study populations

Poverty lines
 Below Poverty Line is an economic benchmark to indicate
economic disadvantage and to identify individuals and
households in need of government assistance and aid
 Since 2008, the last update, we have used $1.25 as the
global line.
 As of October 2015, the new global line will be
updated to $1.90.
 29.8% in India below poverty line-70 th world wide
 'International Poverty Line
An international monetary thresholdunder which an
individual is considered to be living in poverty
 The World Bank has revised its definition and benchmarks
to measure poverty since 1990, with $2 per day income
on purchasing power parity basis
 In 2012, the Indian government stated 22% of its
population is below its official poverty limit
 The World Bank, in 2011 based on 2005's
PPPs International Comparison Program,estimated 23.6%
of Indian population, 276 million people, lived below
$1.25 per day on purchasing power parity
 According to United Nation's Millennium Development
Goals (MDG) programme 270 millions or 21.9% people
out of 1.2 billion of Indians lived below poverty line of
$1.25 in 2011-2012
 Those above poverty line live a fragile economic life.
 The World Bank reviewed and proposed revisions in May
2014, to its poverty calculation methodology and
purchasing power parity basis for measuring poverty
worldwide, including India
 According to the Modified Mixed Reference Period
(MMRP) concept proposed by World Bankin 2015, India's
poverty rate for period 2011-12 stood at 12.4% of the
total population, or about 172 million people; taking the
revised poverty line as $1.90.
 Each state in India has its own poverty threshold to
determine how many people are below its poverty line
 Since 2007, India set its official threshold at Rs 26 a day
($0.43) in rural areas and about Rs32 per day ($0.53) in
urban areas
 These numbers are lower than the World Bank's $1.25
per day income-based definition, the definition is similar
to China's US$0.65 per day official poverty line in 2008.
 In 2011-2012, Puducherryhad its highest poverty line of R
s 1,301 (US$19) a month in rural and Rs 1,309 (US$19) a
month in urban areas, while Odishahad the lowest
poverty thresholds of Rs695 (US$10) a month for rural
and Rs 861 (US$13) a month for its urban areas
Ninth Plan
 In its Ninth Five-Year Plan (1995–2002), BPL for rural
areas was set at annual family income less
than Rs.20,000, less than two hectares land, and no
television or refrigerator.
 The number of rural BPL families was 650,000 during the
9th Plan.
 The survey based on this criterion was again carried out
in 2002 and the total number of 387,000 families were
identified.
 This figure was in force until September 2006.
Tenth Plan
 In its Tenth Five-Year Plan(2002–2007) survey, BPL for
rural areas was based on the degree of deprivation in
respect of 13 parameters, with scores from 0–
4: landholding, type of house, clothing, food
security, sanitation, consumer durables, literacystatus,
labour force, means of livelihood, status of children, type
of indebtedness, reasons for migrations, etc.
 The Planning Commission fixed an upper limit of 326,000
for rural BPL families on the basis of simple survey.
Accordingly, families having less than 15 marks out of
maximum 52 marks have been classified as BPL and their
number works out to 318,000
 BPL for urban areas was based on degree of deprivation
in respect of seven parameters:
roof, floor, water, sanitation, education level, type of
employment, and status of children in a house.
 A total of 125,000 upper families were identified as BPL
in urban area in 2004.
Kerala
 The Government of Kerala is one of the few state
governments which has formulated its own criteria.
 In Kerala there are nine parameters.
 Families which lack access to four or more parameters are
classified as BPL.
The nine parameters
 No land or less than five cents of land
 No house or dilapidated house
 No sanitation latrine
 Family with an illitrate family member
 No regular employed person in the family
 No access to safe drinking water
 Women-headed household or presence of widows or
divorcee
 Scheduled castes and scheduled tribes (SC/ST)
 Mentally retarded or disabled member in the family

recommendations to use Socio-Economic Caste Census,
instead of poverty line, as the main instrument for
identification of beneficiaries and transferring of funds for
social schemes in rural areas

  • 25. Social class  Above 43 Upper Class (I)  33-42 Upper Middle Class (II)  24-32 Middle Class (III)  13-23 Lower Middle Class (IV)  Below 13 Lower Class (V)
  • 27. Limitations  This scale does not emphasize the income aspect  Can only be used for rural subjects  Caste system varies in each state
  • 29.  Per capita monthly income = Total monthly income of the family/Total members of family.
  • 30. The need to update SES scale  Income ranges in the scale lose their relevance following the depreciation in the value of the rupee .  Steady inflation, lower interest rates, and country’s current account deficits are the main factors contributing to fall in the value of currency.  Therefore, it is needed to update the scale regularly for socioeconomic classification of study populations.
  • 33. Methods to update SES scale  Kumar had tried to update Prasad Scale’s income limits using consumer price index (CPI)  Kuppuswamy socioeconomic scale was revised with CPI .  Linking of the scale with price index makes it relevant and meaningful and also provides a opportunity for constant updation .
  • 34. Price index  A price index (plural: “price indices” or “price indexes”) is a normalized average (typically a weighted average) of price relatives for a given class of goods or services in a given region, during a given interval of time  Calculating the CPI for a single item
  • 35. Wholesale price index(1902)  The change in the average price level of 676 commodities traded in wholesale market  Weekly basis availability
  • 36. Consumer Price Index (CPI)  Definition: A comprehensive measure used for estimation of price changes in a basket of goods and services representative of consumption expenditure in an economy is called consumer price index

  • 42. Modified BG Prasad socioeconomic scale  Modified BG Prasad socioeconomic scale is widely used to determine the socioeconomic status .  The BG Prasad scale was formulated in 1961 keeping the base of Consumer Price Index (CPI) for 1960 as 100  Mishra, undertook the important task of revision of family income per month for 1998 using base year 1982=100.Presently the base year has been changed from 1982 to 2001  The Consumer Price Index (CPI) for industrial workers (IW) is used to calculate updated income categories
  • 43. Updating Prasad’s Scale  The BG Prasad scale was formulated in 1961Consumer Price Index (CPI) for 1960 as 100.  This was revised in 1982 by introducing a linking factor of 4.93 to convert CPI (1982) from the new base of 100 to the old base CPI (1960).  Again a need was felt in 2001 to revise the base, which was done by introducing the linking factor of 4.63.
  • 44. Formula updated as for January 2017  CPI [IW]× 4.63× 4.93 ÷ 100.  [ 274 × 4.63) × 4.93 ÷ 100.  = 62.5429=62.5 Class Prasad’s Classification (1961) In Rupees New Starting classes before they are rounded off Modified Prasad’s Classification after rounding off to the nearest Rs. 10/= I 100 & above 6250 6250 & above II 50-99 3125 3130 – 6250 III 30-49 1875 1880– 3130 IV 15-29 937 940-1880 V Below 15 937 Below 940
