Por lo que, viendo estos datos, se puede afirmar con toda seguridad que esta mayor longevidad vendrá acompañada de un crecimiento en la tasa de dependencia, es decir, de un incremento del porcentaje de personas que no trabajan en relación a las que sí lo hacen.
En otras palabras, la proporción de gente que trabaja respecto al conjunto de la población está disminuyendo. Así, según el INE, en 2066, por cada persona en edad de trabajar, habrá en España otra que no estará en edad de hacerlo, porque será menor de 16 años o mayor de 64.
En concreto, la tasa de dependencia se elevará hasta casi el 90%, partiendo del 50% actual.
Por tanto, un menor número de trabajadores va a tener que sustentar a un mayor contingente de jubilados. Aquéllos, por consiguiente, tendrán que pagar cada vez más para que se puedan seguir prestando los servicios sociales a los mayores: pensiones y gastos médicos. La Seguridad Social consumirá, de año en año, una parte de nuestra renta nacional, por lo que aparecen serias dudas sobre la capacidad de garantizar el actual sistema público de pensiones español.

So, looking at this data, we can say safely that this greater longevity will come accompanied by a growth in the rate of dependence, i.e., an increase in the percentage of people who do not work in relation to those that do. In other words, the proportion of people who work on the whole population is declining. Thus, according to INE, in 2066, for each person age work, there will be in Spain another that will not be in age to do so, because it will be 16 years old or older 64. In particular, the dependency ratio will rise to almost 90%, starting from the current 50%.Therefore, fewer workers will have to support a major contingent of retirees. Those, therefore, will have to pay more so that is can continue to provide social services for elderly people: pension and medical expenses. Social Security will consume, from year to year, a part of our national income, making it appear serious doubts about the ability to guarantee the current public pension system Spanish.

So, seeing this data, we can say with certainty that this increased longevity will be accompanied by an increase in the dependency ratio, ie an increase in the percentage of people who do not work in relation to which they do .
In other words, the proportion of people working compared to overall population is declining. Thus, according to the INE, in 2066, for every person of working age, will be in Spain another that will not be old enough to do so, because it will be less than 16 or older than 64.
In particular, the dependency ratio will rise to almost 90%, starting from 50% today.
Therefore, fewer workers will have to sustain a larger contingent of retirees. Those, therefore, will have to pay more and more so that they can continue to provide social services to the elderly: pensions and medical expenses. Social Security consume, year by year, part of our national income, so they appear serious doubts about the ability to ensure the current Spanish public pension system.
