Algengi í aldursflokkum bæði kyn saman
er sýnt í 7. töflu, en eftir kynjum er algengið
þannig miðað við 100.000 ibúa:
60—69 ára: Karlar 14, konur 50,
70—79 ára: Karlar 171, konur 502 og
80 ára og eldri: Karlar 2238, konur 2552.
1 aldursflokkum er litill munur á algengi
meðal karla og kvenna eins og hér kemur
fram. Hin háa tala kvenna í 8. töflu (111
konur og 55 karlar) stafar af hærri tölu
kvenna en karla í elstu aldursflokkum.
