Please don't infer that all people act the same. Some countries use gallons, other liter. What is normal for one people can be weird for other.
Real facts: Spain is losing population. We have one of the lower children by women ratio in the world and the big scam nuked any stability at work for many young couples worsening the situation heavily. The health system has suffered also in the last years. Less funds for public health system means people living less, not more. They should mention this important context in an article about life expectancy.
If we define life expectancy as "the mean number of years of life remaining at a given age, assuming age-specific mortality rates remain at their most recently measured levels" If you have less babies, you have less babies dying in their first years. Your mortality value changes. You have also less young spanish adults doing stupid things and dying young. What about the young spaniards forced to migrate to other countries and that become citizens of other countries? Do the index count a young migrant man from equator or Morocco dying in Spain as spanish mortality?
Statistics are just a model, not the real life. They lie, always. We can build a statistical model to say anything we want. Is the interpretation in the correct context what counts.
