We examine sex-selection in the UK among immigrant families and the gender composition of previous births, conditional on socio-economic characteristics. Our key result is that better-educated immigrants balance their family after the birth of two sons, by having a daughter thereafter. Our study also is the first to estimate the number of missing women among Asian immigrants in a European country, contributing to research on the US and Canada that missing women are also a phenomenon of the developed world.</jats:p> </jats:sec> jats:sec jats:titleJEL codes</jats:title> jats:pJ13, J15, O52, Z13</jats:p> </jats:sec>
