Socioeconomic status (SES) is one of the influential factors which determine the health of an individual. Assessment of SES status relies on multiple factors such as income, education, occupation, and religion. SES reflects a person's social as well as economic status, and researchers have found that people with high SES utilize more health-care facilities and also focus on preventive aspects because of high awareness and vice versa.

Kuppuswamy SES scale and BG Prasad SES scale are the two most widely used SES scales for classifying the people by SES. BG Prasad scale was first introduced in 1961 and was revised by the author himself in 1968 and 1970.[1],[2],[3] It is applicable to both urban and rural population. It is based on per capita monthly income and is widely used in India. Per capita monthly income is computed as:

Per capita monthly income = total monthly family income/total family members

The advantage of using BG Prasad SES scale is that it takes into consideration only income variable and is simple to calculate. However, income variable needs to be updated from time to time. The value of rupee keeps on changing due to monetary inflation, and hence, income criteria may lose its relevance. Therefore, it is important to continuously update the income categories of the scale.


  Revision of BG Prasad Scale Top


The BG Prasad scale was introduced in 1961 considering the base of Consumer Price Index (CPI) for 1960 as 100.[1] The scale was modified in 1982 and 2001 by introducing linking factors to convert CPI (1982 and 2001) from the new base of 100 to the old base CPI (1960). The linking factors for 1982 and 2001 were 4.93 and 4.63, respectively.[4]


  Calculation of the New Income Ranges Top


CPI − Industrial Workers (IW) for September 2016 = 277

Multiplication factor = Current index value (275)/Base index value in 2001 (100) = 2.77

The new income value can now be calculated using the following equation:

New income value = multiplication factor × old income value × 4.63 × 4.93

where 4.63 and 4.93 are the linking factors given by the Labour Bureau.

The updated values for the per capita monthly income (in Rs./month) for September 2016 are given in [Table 1].

As CPI-IW value will be updated at frequent intervals, there is a need for simultaneous updating of all socioeconomic classifications which consider income as a parameter. Dynamic nature of inflation may pose a risk to the validity of any published update on SES. Hence, an online tool has been made available to enable real-time update of the Prasad's social classification.[5] The online tool will retain its validity till the time the base year (2001 at present) for CPI-IW is next changed.
