Nettetactual 1989 rates. At first Lee and Carter worried about giving too much weight to a single year, but eventually concluded that it was better to update the age- pattern. The next step in the forecast is to construct a full life table from the age-specific mortality rates. This can be done using standard techniques, so I’ll skip the details.
