I was able to find this: https://datacenter.kidscount.org

No real trends there for any race in particular. Maybe one for black teens over the last 5 years.

i don’t have evidence about the kids, but this analysis covers the 25-54 age group.
Since 2000:
white death rates up 11%
Hispanic death rates down 14%
black death rates down 23%
