*Since the accident/violence rank is from lowest to highest levels, and since the life expectancy rank runs from highest to lowest life expectancy, lower numbers are better in both cases.
** Note that the life expectancy rankings in this table rank only the countries compared, and therefore differ from the rankings in the source table, which includes 222 nations.  However, the relative rankings of the 21 countries listed here match their relative rankings from the source.
