Geographic crosswalk interpolation weight for adults 25 years and older

We don’t have plans to add a weight for adults 25 years and older. I agree that it’d be useful for exactly the setting that you’re interested in (educational attainment data), but it’s unclear how much value it would add over the existing weight for adults (18 years and older). I expect there’d be a few places, particularly around college campuses, where the weights could differ substantially, but I’d otherwise expect them to be quite similar. For now, I’d recommend using the adult weight.

Alternatively, you could use our block-level crosswalks to generate your own 25-and-over weighting following the guidance I provided in this post. (If you go that route, I’d be curious to hear if you found many large differences from the adult weights!)
