President Donald Trump has called for a “new” census that excludes undocumented migrants from its count. If this new census were realized and used for the core functions of the current one — determining how seats in the Electoral College and the US House of Representatives are apportioned and how some federal funding is distributed — it would have wide-ranging implications for the US.

Trump has instructed the Commerce Department to change the way the Census Bureau collects data, seeking to exclude immigrants in the country illegally.

President Donald Trump announced in a social media post on Thursday that he has directed the Department of Commerce to begin work on a new US census that excludes undocumented immigrants from the population count.

President Donald Trump has instructed the Commerce Department to have the Census Bureau start work on a new census that would exclude immigrants who are in the United States illegally from the head count which determines political power and federal spending.

The next census will be taken in 2030. According to NBC San Diego, Trump announced that he planned to omit undocumented immigrants from the count last Thursday. Many civil rights groups have objected to the potential change.
