In 2018, Portuguese emigration to the US registered a further decrease (-5% in 2018, -7% in 2017). This new decrease reinforces the reversal of the upward trend that had occurred in 2016 (17% increase and more than a thousand entries). The variation in the number of Portuguese inflows into the USA during this century has, in general, followed the variations in total immigration in that country, which, in 2018, also had a decrease (-2.7%).
