In the most recent edition of the multilevel dataset for ESS9, ESS9MDWe03.1, we have been alerted to an error in variables c_gdppc_1990 - c_gdppc_2019 ("[COUNTRY] GDP per capita at current prices, US Dollars").

All variables will be corrected in future releases.

In the meantime, we would recommend users to either omit these variables altogether from any analyses or apply the corresponding variables (restricted to c_gdppc_1990 - c_gdppc_2017) published in ESS8MDWe02.1.

A new version of the ESS9 integrated file (edition 3.2) was published on 24 November 2023.

The new release is due to some corrections in the religion variables for Cyprus and the education variables for Norway.

For more information, see version information for the ESS9 integrated file on the ESS Data Portal.

Error in ESS9 weights and the sampling documentation for Cyprus. 

Recent information reveals that an unequal-probability clustered design has been used in rural areas of Cyprus instead of a single stage design, upon which the current weights and sample design indicators are based. True design effects are thus likely substantially higher than those estimated using the current weights and psu indicators. The result of this is a probable under-estimation of standard errors for analysis of the Cypriot data for ESS9, with some modest effects on substantive estimates also possible. 

We will get back with more information on possible corrected weights and sample design variables.

The Albanian data for ESS round 9 was released 03.12.21. Albania will not be included in the ESS9 integrated file, due to unresolved issues with the quality of the data.

Data and documentation is accessible from the ESS Data Portal.

The Romanian data for ESS round 9 was released 10.09.21. Romania participated on a pilot basis in Round 9 and will not be included in the ESS9 integrated file.

Weights (ANWEIGHT, DWEIGHT, PSPWGHT) will be included in a future update later in 2021.

Data and documentation is accessible from the Romanian country page.

The new release is due to some corrections in the Hungarian and Croatian data. For further details please see ESS9 version notes.
