Extracting Google Trends interest by region: countries, states and US metros

Google Trends interest by region ranks places by the share of their searches that went to a term, on a 0–100 scale where 100 is the place with the highest share. A small place can rank first: Wyoming scored 100 for sunscreen in the United States over 5 years, ahead of Hawaii at 82 and California at 53, measured on September 30, 2026.

Google Trends interest by region for sunscreen, top 10 US states led by Wyoming

Google Trends interest by region is the ranking of places by the share of their searches that went to a term in a time range. Each place gets a value from 0 to 100, where 100 is the place where the term took the largest share of searches.

A small state ranks first in Google Trends because the value measures share, not volume. Google divides each data point by the total searches of the geography it represents, so places with the most searches do not always rank highest, according to Google Trends Help.

The ranking comes from Google Trends for the United States over the past 5 years, measured on September 30, 2026.

4 region resolutions exist in Google Trends, and 3 region resolutions work in Kwerix’s tests on September 30, 2026.

  1. Country, for worldwide requests.
  2. Region, such as US states or Spanish autonomous communities.
  3. Metro (DMA), the US designated market areas.
  4. City, which returned no data for the United States and Spain in the same tests.

There are 3 steps to extract interest by region via the Google Trends API.

  1. Switch on includeInterestByRegion.
  2. Choose regionResolution: AUTO, COUNTRY, REGION or DMA.
  3. Read interestByRegion in each row: geoCode, geoName and value.
"interestByRegion": [
  { "geoCode": "US-WY", "geoName": "Wyoming", "value": 100 },
  { "geoCode": "US-HI", "geoName": "Hawaii", "value": 82 }
]

Regional values can move by a point or two between requests, because every request draws on a sample of searches, as the guide to Google Trends accuracy explains.

Interest by region vs interest over time

Interest by region answers «where», and Google Trends interest over time answers «when». Local content and ad budgets start from the first; publishing calendars start from the second.

  • The Google Trends API returns interest by country, region or US metro for every keyword when includeInterestByRegion is on.

Is interest by region the number of searches in each place?

No. Interest by region is each place's share of its own searches, scaled 0–100, so a small state can score higher than a large one with more searches.

Can I get Google Trends data by city?

Not reliably. In Kwerix's tests on September 30, 2026, city resolution returned no data for the United States and Spain, while regions and US metros worked.
