Using tables to find number of Black people in Allegany county

Hi all, I hope everyone is healthy.

Here is my question.

These two tables (P1, 2020: DEC Redistricting Data (PL 94-171), and DP05 (2020: ACS 5-Year Estimates Data Profiles)) show that there are at least 757 Black or African American people in Allegany county, possibly more.

On the other hand, this table (B11001B) show that there are 19 households with a householder who is Black or African American and this table (B11002B) shows 29 people in family households with a householder who is Black or African American.

That is, while there are at least 757 Black or African American people in Allegany county, there are only 19 households with a Black or African American householder, and only 29 people living in family households with a Black or African American householder.

That means that 96% of Black or African American people in Allegany county are living in conditions that are NOT households with a Black or African American householder. Is that correct? Am I misunderstanding something?

P1, 2020: DEC Redistricting Data (PL 94-171), shows 829 Black or African American alone people in Allegany county
