Number of foreign-born individuals in Turkey by the year of arrival, 2004–2017.Sources: Household Labour Force Survey 2017 and author’s own calculations.Notes: The figure shows the number of foreign-born observations living in Turkey. “Syrian refugees” are obtained by subtracting the average number of foreign-born individuals during the 2004–2010 period (the so-called ex-ante standard migrants) from the total number of observations in each of the years between 2011 and 2017 (ex-post migrants).

Propensity scores, before and after matching: (a) before matching and (b) after matching.Sources: Household Labour Force Survey 2017 and author’s own calculations.Notes: The box plots show propensity scores distributions. The three horizontal lines of the blue boxes denote the third quantile, the median, and the first quantile, from top to bottom. (a) shows the distribution before matching for foreign-born families who arrived, respectively, between 2004 and 2010 and between 2011 and 2017. (b) splits the scores of 2011–2017 migrant families between those families matched (ex-post “standard” migrant families) and those unmatched (Syrian families).

Syrian refugees’ population pyramid, HLFS vs. DGMM.Sources: Household Labour Force Survey 2017, Directorate General of Migration Management, and author’s own calculations.Notes: The figure shows the proportion of Syrian refugees in a number of age groups from two sources: the HLFS 2017 and the DGMM. A chi-square test cannot reject that the HLFS and DGMM data are drawn from the same distribution. It also shows the proportion of ex-post “standard” migrants for comparison.
