Comparing CVAP to other (non-ACS) variables

Hi!

I want to compare race and ethnicity in CVAP (county-level) to voting-related data, such as

- number or percentage of voters whose registrations are cancelled in a given time frame  (data source is the TX Secretary of State)

- percentage of voters in "Suspense" status (data source is either the TX Secretary of State, or individual counties)

I am looking for possible correlations with the racial background of CVAP. For example: whether the percentage of CVAP which is Black/African American is correlated to the percentage of voters cancelled in a given year.

Ideally, I would have a CVAP estimate associated with each calendar year which can be compared to cancellations that occurred within the same year.

What is the right time frame to compare? For example; if I have the percentage of registrations cancelled in 2023, should I compare with the CVAP from 2019-2023? 

thanks in advance,

Andrea
