Thank you ESRI Staff for providing ACS Living Atlas data! Is there a way to identify the vintage of the ACS data? This is an important consideration to data users so they can cite which version of the estimates are being used and can trust that they are using the most current version. Perhaps adding an attribute indicating " 2021 ACS 5-Year Estimate" would be one way for this to happen or consider indicating the vintage in the pop-up.
Thanks!
