<p>India has been measuring <code>inflation</code> since the 1960s, but it wasn't until 2012 that the government started publishing data on <code>CPI inflation</code>. Before 2012, the government only published data on <code>WPI inflation</code>.</p>
<p><code>WPI inflation</code> is a measure of <code>inflation</code> for the <code>wholesale</code> market, which is where businesses buy goods and services from each other. <code>CPI inflation</code> is a measure of <code>inflation</code> for the <code>consumer market</code>, which is where households buy goods and services for their own use.</p>
<p>The government decided to switch from <code>WPI to CPI</code> inflation because CPI inflation is a better measure of inflation for the <code>average household</code>. WPI inflation can be volatile, and it can be affected by factors that don't directly affect households, such as changes in the price of oil. CPI inflation is more stable, and it's a better measure of the cost of living for households.</p>
<p><code>CPI-IW</code> is a different type of CPI that measures inflation for industrial workers. It's calculated using a different basket of goods and services than the regular CPI, and it's weighted differently. <code>CPI-IW i</code>s used by the government to set <code>minimum wages</code> for industrial workers.</p>
<ul>
<li><code>WPI</code> Inflation   -- &gt; Inflation for the <code>wholesale</code> market   -- &gt; 1960s</li>
<li><code>CPI</code> Inflation   --&gt; Inflation for the <code>consumer</code> market --&gt; 2012</li>
<li><code>CPI-IW</code> Inflation --&gt; Inflation for <code>industrial</code> workers --&gt; 1970s</li>
</ul>
<p>The inflation data on <code>Macrotrends</code> is for <code>CPI inflation, not WPI inflation.</code> The data is sourced from the <code>Reserve Bank of India (RBI), </code>which  publishes data on <code>CPI inflation</code> on a monthly basis.</p>
<p>RBI uses the <code>CPI</code> to set <code>monetary policy</code>, and the government uses the CPI to index government benefits, such as <code>pensions</code> and <code>welfare payments</code>.</p>
<p>RBI did not publish <code>CPI</code> data before 2012 .  CPI data on Macrotrends is for CPI-IW, not CPI. <code>CPI-IW</code> data on Macrotrends is the <code>Labor</code> Bureau, Government of India. It does not explicitly state but that is the  case in fact.  Data on Macrotrends is weighted differently than the CPI. The CPI is weighted using a <code>Laspeyres formula</code>, while the CPI-IW is weighted using a <code>Paasche formula.</code></p>

Yes, I understand this - my question is what is the inflation which is mentioned in https://www.macrotrends.net/countries/IND/india/inflation-rate-cpi - the page says "Inflation as measured by the **consumer price index** reflects the annual percentage change in the cost to the average consumer of acquiring a basket of goods and services that may be fixed or changed at specified intervals, such as yearly" - so it's not WPI? Where did they get it from? They haven't specifically said it's CPI-IW?

Did RBI publish CPI data before 2012? The NDTV article says that India published CPI for the first time in 2012. So how does Macrotrends have data from 1960? Is it CPI-IW - is there any source for this?

Macrotrends  provides a disclaimer on its website that states that the CPI data on its website is from the Labour Bureau. The disclaimer states:

"The consumer price index (CPI) data on this page is from the Labour Bureau, Government of India. The CPI is a measure of the change in prices of a basket of goods and services consumed by urban households."

https://www.rbi.org.in/Scripts/PublicationsView.aspx?id=2905 compares the CPI and CPI-IW in India CPI is weighted using a Laspeyres formula, while the CPI-IW is weighted using a Paasche formula. based on the comparison of this you can infer its CPI  IW not CPI

I am getting conflicting reports about this.

[India's first-ever CPI-based inflation rate at 7.65% in January 2012](https://www.ndtv.com/business/indias-first-ever-cpi-based-inflation-rate-at-7-65-in-january-2012-298172)

> India’s **first ever annual** inflation rate, based on the consumer price index (CPI), was 7.65 per cent for the month of January 2012, government data relased on Tuesday showed.

This seems to say that they started measuring CPI inflation only in Jan 2012

However, I also found this from 2009,

Macrotrends also gives CPI inflation for India from the 1960s - <https://www.macrotrends.net/countries/IND/india/inflation-rate-cpi>

If India didn't measure CPI before 2012, how does Macrotrend have data from 1960

Another confusing data point is here from 2010

[Inflation in India highest amongst major developing nations](https://economictimes.indiatimes.com/news/economy/indicators/inflation-in-india-highest-amongst-major-developing-nations/articleshow/6266840.cms)

So when did India actually start measuring CPI inflation?

### Answer by username_1 on 2023-06-18. Score: 1

India has been measuring `inflation` since the 1960s, but it wasn't until 2012 that the government started publishing data on `CPI inflation`. Before 2012, the government only published data on `WPI inflation`.

`WPI inflation` is a measure of `inflation` for the `wholesale` market, which is where businesses buy goods and services from each other. `CPI inflation` is a measure of `inflation` for the `consumer market`, which is where households buy goods and services for their own use.

The government decided to switch from `WPI to CPI` inflation because CPI inflation is a better measure of inflation for the `average household`. WPI inflation can be volatile, and it can be affected by factors that don't directly affect households, such as changes in the price of oil. CPI inflation is more stable, and it's a better measure of the cost of living for households.

`CPI-IW` is a different type of CPI that measures inflation for industrial workers. It's calculated using a different basket of goods and services than the regular CPI, and it's weighted differently. `CPI-IW i`s used by the government to set `minimum wages` for industrial workers.

* `WPI` Inflation -- > Inflation for the `wholesale` market -- > 1960s
* `CPI` Inflation --> Inflation for the `consumer` market --> 2012
* `CPI-IW` Inflation --> Inflation for `industrial` workers --> 1970s

The inflation data on `Macrotrends` is for `CPI inflation, not WPI inflation.` The data is sourced from the `Reserve Bank of India (RBI),` which publishes data on `CPI inflation` on a monthly basis.

RBI uses the `CPI` to set `monetary policy`, and the government uses the CPI to index government benefits, such as `pensions` and `welfare payments`.

RBI did not publish `CPI` data before 2012 . CPI data on Macrotrends is for CPI-IW, not CPI. `CPI-IW` data on Macrotrends is the `Labor` Bureau, Government of India. It does not explicitly state but that is the case in fact. Data on Macrotrends is weighted differently than the CPI. The CPI is weighted using a `Laspeyres formula`, while the CPI-IW is weighted using a `Paasche formula.`
