Based on millions of classified ads published on the platform Avito, RBC analyzed the prices in 31 categories of non-food goods and services. The first derivative product was index of well-being

Government agencies monthly report on inflation in the country, research company trying to calculate the cost of the consumer basket. We decided to launch the project on monitoring of prices in the cities of Russia and regularly measure the standard of living and how changes in the cost of consumption in different localities of the country. Our partner in the project was the Internet company Avito — the largest platform of ad with more than 30 million unique users per month. As of 13 February on the portal was placed almost 34 million ads, to information on the company’s website.

For research in collaboration with analysts Avito we have selected the most popular on the secondary market non-food goods and services, put them in a category 31 — from the most expensive real estate, automobiles, motorcycles, equipment and electronics to the most available, for example, clothing and footwear, children’s furniture, toys. So we got his version of the conventional “basket of consumption”.

In selected categories, we have analyzed millions of ads placed on the site in the third quarter of 2016 (at the time of the study it was the latest available and the full time period). Next was calculated the average prices for individual products and services. This time we have restricted the sample of 36 cities of Russia — there where, according to official statistics, more than 500 thousand people.

The first product on the results of monitoring of prices in the secondary market was the wealth index. It reflects the average level of the price formed us a “basket of consumption” in each of the cities included in the study sample. More than the final index and, accordingly, higher position of the settlement in the total score, the higher the level of prices and, consequently, more expensive cost of living for this city. In the final revision of the Index RBC/Avito was only 26 cities, the rest dropped out because of insufficient data.

Most expensive city in the predictable became Moscow. The last place was taken by Ulyanovsk — he had been most of the budget for consumption by city Index RBC/Avito. Of the 26 cities included in the final version of the study, only nine “basket of consumption” consists of a complete list. If you compare those cities among themselves, are investigated: the average cost of a complete set of goods and services in Moscow is more than twice higher than in Omsk, Volgograd and Saratov. The difference between Moscow and St. Petersburg is not so big: the capital in our set was on average more expensive by about 25%.

The sample for mapping the dynamics we have not yet large, therefore, we first compared the average prices for a short period of time — during the third quarter of 2016. And Moscow at the increase in the value of the “basket of consumption” was not the first capital ranked only seventh place with an index of 2.3 percent”. The most appreciated three months in the city, as shown by the index of the RBC/Avito became Samara: “basket of consumption” for local residents in this city increased in price by almost 4% for the quarter. In this case most notably for the quarter decreased price tags in Kemerovo — the cumulative average price of a “basket of consumption” here dipped by almost 10%. Stability, or a barely perceptible change of prices for the period showed Chelyabinsk: as the analysis information in posted on Avito ads, the average total price of a “basket of consumption” only changed by +0.2 percent.
