SQL used to extract data:
SELECT MyTbl.DoseRange, MyTbl.CareerLen, Count(*) AS NumPersons FROM MyTbl WHERE (((Year([MaxMon]))<=[LastYearOfWork])) GROUP BY MyTbl.DoseRange, Tbl.CareerLen; SELECT Round(Avg(DateDiff('d',[MinMon],[MaxMon])/365),2) AS AvgCareerLen, Round(Avg([TotDDE]),2) AS AvgCareerDose FROM MyTbl WHERE

(((MyTbl.DoseRange)>1) AND ((Year([MaxMon]))<=[LastYearOfWork]));
CareerLen is determined by establishing the difference between the last Monitoring_End_Date and the first Monitoring_Begin_Date.
