A technical assistance mission assisted the Statistics Agency under the President of the Republic of Uzbekistan (SA) in conducting a major revision of national accounts time series. Based on the results of the 2023 survey on non-observed economy (NOE) in hotels, restaurants, and other services, the 2024 major revision increases the nominal GDP for 2017–2023 in the range of 10–12 percent. The mission reviewed the results of the 2024 major revision and provided recommendations for improvement before their publication. These improvements to data and methods will improve the understanding of the Uzbekistan economy, both for domestic policymaking and international surveillance.
