I've used ACS and IPUMS data previously for research while at university. What are your thoughts on the proposed "differential privacy" changes [0] coming this way? Is it a "sky is falling" kind of situation?
It's not really my area of expertise, but from what I understand it will severely limit what policy and demographic research can be done with the data. There's a working paper on the page you linked to which has more information: https://assets.ipums.org/_files/mpc/MPC-Working-Paper-2018-6....
