- What it measured
- SHED 2025 item L0_c (“My adult child(ren) age 18 or older - First, do each of the following people currently live with you?”), counting responses 1=Yes. Computed from the Federal Reserve's public-use microdata with its post-stratification weight WEIGHT. The public file has no design variables or replicate weights, so the standard error follows the Fed's documented design effect: SE = √(deff · p(1−p)/n), deff = 1.144 (the Fed's 1.14, or the Kish design effect of these weights if larger); unweighted n = 12,934.
