As a consequence of the war in Ukraine, CTIS response rates have fallen, and the demographic composition of the survey samples have shifted in Ukraine and Russia in addition to some nearby countries, including Poland and Belarus.
Starting February 24, 2022, data from these countries should be interpreted with caution. CTIS sampling is not being suspended in either country at this time. Meta continues to monitor the data in these countries and will reevaluate the sampling decision as needed.
