Hi CrUX users,

This is your monthly announcement that the latest dataset has been published to BigQuery.

The 202209 (September 2022) dataset is now available and it covers 17,715,277 origins, an increase of 5.7% over last month. Here’s a look at origins' Core Web Vitals performance this month:

  • 54.5% of origins had good LCP

  • 94.8% of origins had good FID

  • 72.4% of origins had good CLS

  • 41.4% of origins had good LCP, FID, and CLS

The CrUX API now includes a collectionPeriod object with firstDate and endDate fields representing the beginning and end dates of the aggregation window. An example is provided below:

    "collectionPeriod": {

      "firstDate": {

        "year": 2022,

        "month": 10,

        "day": 9


      "lastDate": {

        "year": 2022,

        "month": 9,

        "day": 12



This allows better understanding of the data and whether it's been updated yet for that day or is returning the same data as yesterday.

Note that the CrUX API is approximately two days behind today's date since it waits for completed data for the day, and there is some processing time involved before it is available in the API.

The new collectionPeriod object has been added to our documentation at
