Decrease in out-of-home events	Drop in the number of out-of-home events of cell-phone users, relative to the baseline data (March 2). The indicator first calculates the daily median for out-of-home events of all cell phone users, and then calculates the median over quarterly periods. Data before March 1 is set to zero and the fourth quarter ends on November 30.h)	municipal	0.00 [0.00]	−0.21 [0.17]	−0.28 [0.15]	−0.32 [0.15]

Distance	Weighted average of direct distance in km from state capitals in Mexico to the state capital in the US state where migrants reside using the haversine formula. For exposure to unemployment, the average (weighted) distances between origin and destination is calculated depending on the distribution of migrants across the US.c) d)	state	2016.13 [526.60]
