\begin{tablenotes}
\small
\item See notes to previous table. This model is a regression of the change in residual wages from 2014 to 2018 on the 2018 foreigner share, calculated using the GEIH or Census as a share of the 2018 population. The instrument is created analogously (interacted with the national migration rate from the GEIH or census). In no case does the K-P Wald stat fall below 10.
