The latest information available indicates that at the end of the financial year 2006-07 there were around 400,000 men and just over 600,000 women between state pension age and age 80 who had accrued between 30 and 43 qualifying years or 30 and 39 qualifying years respectively for basic state pension.
However, individuals with less than 44 or 39 qualifying years can still qualify for a full basic state pension under the current arrangements.
Entitlement to a basic state pension depends on a number of factors including the number of qualifying years accrued, home responsibilities protection and the spouse's contribution record.
