It turns out, however, that these comparisons are much more difficult to make. Australia and Canada have a lot of families migrating to the US as well. In an international 2018 comparison, researchers at the Migration Policy Institute found much more similarities to the US than is usually understood. Relative to their populations, Australia, Canada, and the US all admit about the same number of people through family migrants. Per 1,000 people, the US admits 2.1 family immigrants. On the same scale, Australia admits 2.6 and Canada 2.0. Seen this way, the US is behind on economic migrants, But the US is not so different on family immigration.
