My DV is binary. Would this be the reason why most my variance is zero. Is there a way to correct for this or is both the county level and zip code level neighborhood disadvantage variable just not significant?
Thanks Maartin for the help you have provided.

Your model has a major problem, most of the variances are zero (remember
1e-16 means 0.00000000000000001).
Hope this helps,
