The article titled “Socioeconomic status scales-modified Kuppuswamy and Udai Pareekh's scale updated for 2019” published on June 2019 in the esteemed journal of Family Medicine and Primary Care is a well written one. In the field of Family medicine, Socio-Economic Status is one of the most important determinants of health status of the family. The researchers in the field of family medicine and primary care should be updated with regards to the income limits for classification of socio-economic status. Kuppuswamy SES scale and its modifications used both in urban and rural areas, is based on 3 variables – Monthly total family income, Occupation and Education of the head of the Family. This scale focuses on the Total Monthly family income as a whole in the determination of socio-economic status compared to other scales such as BG Prasad scale, which focus on Per capita monthly income. As pointed out in the article, there was a need for update in the base year of All India Consumer Price Index (CPI) for Industrial workers (IW) from 2001 series. Recently, the Labour Bureau, government of India has revised the base year of the existing CPI-IW series from 2001 = 100 to a more recent, 2016 = 100 in October 2020., The aim of this letter is to update the income ranges for Modified Kuppuswamy scale based on the recently released All India CPI-IW with 2016 as baseline (=100). As shown in [Table 1], the baseline year was used as 2001 (=100), prior to the current release. The Labour Bureau, government of India on monthly basis releases the CPI-IW, which in turn decides the income limits.

Table 1 shows the CPI (IW) from January 2016 to September 2020. The old baseline, 2001 (=100) was used till the month of august 2020. New baseline series, 2016 (=100) has been adapted for the month of September 2020. The linking factor between the old (2001) and new series (2016) is 2.88. CPI (IW) for September 2020 with 2016 (=100) as baseline is 118. Using these value, the CPI (IW) for September 2020 was 340 as shown in [Table 1] with 2001 (=100) as baseline. That is if the old baseline had been used, the CPI (IW) for September 2020 would be 340.
[Table 2] shows the updated income limits of Modified Kuppuswamy scale for September 2020 derived from Baseline 2001 limits as derived by Wani RT (2019). Calculation of 2016 baseline limits are essential for future use as multiplication factor has to be applied to this baseline till the next baseline year for CPI (IW) is announced. This may be atleast 5 years away as planned by the Labour Bureau, Government of India. [Table 2] describes the method of calculation used for calculating the income limits for Modified Kuppuswamy scale using the various linking factors.
|Table 2: Modified Kuppuswamy scale total monthly family income limits updated for September 2020 in rupees|

2020 September CPI (IW) = 118 (with Base 2016 = 100).,
Total Family monthly income limits (2016) = 2001 value × 2.88,
Total Family monthly income limits (September 2020) = 2016 value × 1.18,
This updated Modified Kuppuswamy scale will help the researchers to update the income limits while applying it in their day to day research. By applying their state and month specific values of CPI (IW) updated regularly on the last working day, of the succeeding month, researchers can improve the validity of the Socio-economic status of the family.
