Hello, I'm not familiar with U.S. data standards. While reviewing the data in your REP and trying to analyze it, I find many elements very counterintuitive. One example among many is the average lifespan of AIAN (American Indian/Alaska Native) in the picture here. Could you clarify this for me? Thank you!

Thanks for this question! The occurrence of large values for life expectancy (LE) is often due to the relatively small population size of a group. For a small group of people, LE is sensitive to the number of deaths in an age group. We usually see a large confidence interval for small groups, implying large uncertainty in LE estimation. The CHRR mortality calculator can be used to replicate the Life Table methodology we use to calculate this measure. The life table methodology is a complex method which uses information at each age to understand the probability of a person moving through that age group into the next one and is thus more cumulative than a typical mortality calculation. Therefore, LE is sensitive to both small populations and larger than expected number of deaths in the youngest age groups. The values over 100 years are accurate, but they are surprising. They should be interpreted with the confidence interval to reflect the high level of uncertainty they carry. |
