We have to realise how old, how very old, we are. Nations are classified as "aged" when they have 7 per cent or more of their people aged 65 or above, and by about 1970 every one of the advanced countries had become like this. Of the really ancient societies, with over 13 per cent above 65, all are in Northwestern Europe. At the beginning of the l980's East Germany had 15.6 per cent, Austria, Sweden, West Germany and France had 13.4 per cent or above, and England and Wales 13.3 per cent. Scotland had 12.3 per cent. Northern Ireland 10.8 per cent and the United States 9.9 per cent. We know that we are getting even older. and that the nearer a society approximates to zero population growth, the. older its population is likely to be -- at least, for any future that concerns us now.
To these now familiar facts a number of further facts may be added, some of them only recently recognised. There is the apparent paradox that the effective cause of the high proportion of the old is births rather than deaths. There is the economic principle that the dependency ratio ?the degree to which those who cannot earn depend for a living on those who can ?is more advantageous in older societies like ours than in the younger societies of the developing world, because lots of dependent babies are more of a liability than numbers of the inactive aged. There is the appreciation of the salient historical truth that the aging of advanced societies has been a sudden change.
If "revolution” is a rapid resettlement of the social structure, and if the age composition of the society counts as a very important aspect of that social structure, then there has been a social revolution
in European and particularly Western European society within the lifetime of everyone over 50. Taken together, these things have implications which are only beginning to be acknowledged. These facts and circumstances were well to the fore earlier this year at a world gathering about aging as a challenge to science and to policy, held at Vichy in France.
There is often resistance to the idea that it is because the birthrate fell earlier in Western and Northwestern Europe than elsewhere, rather than because of any change in the death rate, that we have grown so old. But this is what elementary demography makes clear.
Long life is alt-ring our society, of course, but in experiential terms. We have among us a very much greater experience of continued living than any society that has ever preceded us anywhere, and this
will continue. But too much of that lengthened experience, even in the wealthy West, will be experience of poverty and neglect, unless we do something about it.
If you are now in your thirties, you ought to be aware that you can expect to live nearly one third of the rest of your life after the age of 60. The older you are now, of course, the greater this proportion will be, and greater still if you are a woman. Expectation of life is a slippery figure, very easy to get wrong at the highest ages. At Vichy the demographers were telling each other that their estimates of how many old there would be and how long they will live in countries like England and Wales are due for revision upwards.
