This study analyzes the changes in two cross-border processes: employment and giving birth in the u nited s tates among the northern border populations of m exico between 2000 and 2010. v arious statistical methods are used to analyze the trends and the changes in the socio - economic prof iles of those who perform these practices. While the numbers of cross-border workers dropped, cross-border births increased; people with higher levels of education be - came increasingly represented in both categories. These results suggest that this border has become a more selective blockade for transborder interactions.
