But the percentage of women who give birth who are 35 or over is small--less than 4 % --plus the fact that, under the terms of the Genetic Health Law, the government subsidizes amniocentesis during pregnancy, so that the absolute number of babies born with Down's is still fewer than to women under 35.
但原本卅五歲以上的產婦人數就少，不到百分之四，再加上有優生保健法照顧，由政府補助在懷孕時做羊膜穿刺檢查，生下唐氏兒的人數反而較卅五以下者為少。
