Below-median income across 27 ZIPs means the county average is a compromise. Sort by population, save the largest urban ZIP and one sparse code, then compare - that pair usually shows whether density or income is doing the work inside Lake.
Save two ZIPs from the table into your shortlist, then open a compare link - that is the return path a static county summary cannot replace. All figures here come from Census ACS 2023 5-Year Estimates and USPS ZCTA files.
