Missingness patterns

The first table shows the number of missings per variable, the second table, using the indexes from the first, shows missings in which variables tend to occur together. Most variables of interest in this study are derived from these dates and so these patterns can show many cases did not have the data to calculate e.g. paternal loss (those lacking either the father’s death date, the anchor’s birth date or both).
