To determine the population of the various states for the purpose apportioning Representatives to congress and Electors to the Electoral College.
Representatives to congress are elected by Citizens of the United States.
Representatives to Congress represent the voters of the district from which they are elected.
It logically follows that citizens should be counted in the census and that non-citizens who do not have the right to vote should not be counted for the purposes of apportionment.
If there is no differentiation in the census between citizens and non-citizens then apportionment can only done by the total population of a state and states with fewer non-citizens would be penalized in their representation in Congress and the Electoral College.
But of course, this is the Democrats plan. Flood the Democrat controlled areas with illegal aliens boosting the population of Democrat controlled metro areas taking permanent control of the House.

That's right.
Ambassador's and their staff from foreign countries live in our country. Although, small in size by comparison, should they be counted in our census? Of course not.
There are lots of people who are temporarily living in our country, for example, on business, on vacation or visiting relatives over the course of a month or two. Should they be counted in our census as well if they happen to be living in the house/condo/apartment at the time the census taker passes by? Of course not.
Only citizens should be counted.
