Declining mortality rates have led to substantial increases in life expectancy. This is because mortality rates reflect the number of deaths in a population, while life expectancy is the average number of years a person is expected to live. As mortality rates decrease, fewer people are dying prematurely, which means that more people are living longer and contributing to a higher life expectancy. This trend has been observed in North America and many other regions of the world.
