^aNonmarital fertility ratios (NMFRs) computed from FFS data include all live births reported by female respondents to have occurred in the year(s) the survey was undertaken and in the last three full years before the survey started. In Austria, for instance, the survey was fielded in 1995–96, so all 1992–96 births are included. They are compared with the closest calendar year statistic available from national birth registration (Source: FFS Standard Reports, Table 1).

^bThe survey for Belgium covers only the Flanders region.

^cIn these countries, data to estimate childhood trajectories were not available.
