Hi. I'd like to calculate (for a given location) the percentage of the total population that is born in a given country. These counts are available in table B05006 (PLACE OF BIRTH FOR THE FOREIGN-BORN POPULATION IN THE UNITED STATES). The universe for this table is not total population, but Foreign-born population excluding population born at sea.
So to have total population as a denominator, I will need to pull total population from another table, such as B05001 (NATIVITY AND CITIZENSHIP STATUS IN THE UNITED STATES). Is this okay to do?
Additional information that may be helpful:
In B05001, the sum of U.S. citizen by naturalization and Not a U.S. Citizen should equal the total foreign born population, the universe of B05006.
I compared the Total figure from B05006 with the sum of these two variables from B05001, to see if they were the same for all geographies. The results are that for 99.9% of geographies, these amounts are the same. For about 199 geographies (out of about 178,000), the values are different. At the national level, there is a difference of 491 out of 41.7 million. So they're pretty close.
