Our US Constitution dictates that we count our population every 10 yrs so that we can determined (among other things) the number of seats for each State in the House of Representatives in Washington DC. Gerrymandering, legal questions about the "citizenship question", cyber-security for taking the census online & the costs, est. to be higher than the 2010 US Census of $12.3 Billion. These are my noted problems for this April, 2020 Census:
-- any mistakes & it's a 10 yr mistake
-- cybersecurity systems & our ability to take the census online safely
-- legal problems (now in the court) of the "citizen question"
-- shortage of census workers
-- field testings were cut short
-- bankrupt printer of the 2020 Census
-- Finally if the schedule stays true, the 1950 US Census should be released on April, 2020 (every 70yrs release of US Census reports.)
