Thanks for explaining, but I have to strongly disagree. If the costs for children of citizens are counted as part of the childrens' net fiscal impact ("citizen cost"), and the costs for the children of immigrants are also counted as part of the childrens' net fiscal impact (again "citizen cost"), then i fail to see the problem with Cato institute's methodology. It's fundamentally the same as if immigrants had zero children, but US citizens of comparable socioeconomic circumstances had an equivalent number of children. It gets factored in for the children; not the parents, and it happens consistently.
