Note. B–W = Black–White; CI = confidence interval; IMR = infant mortality rate. Rate ratios calculated as (Black IMR/White IMR), all conducted and presented as 3-y rolling averages.
a
The numbers were rounded to a single decimal point to comply with editorial guidelines. The percent change was calculated based on the formula [1- (2012 rate/2000 rate)]*100 using numbers to 2 decimals.
b
Signifies racial IMR equality by the year 2050.
*P < .05.
