trated with data on marital stability from two waves of the National S
urvey of Families and Households. First, the advantages of event histo
ry analysis are described. Second issues regarding data collection met
hods are briefly reviewed The final three sections explain statistical

fluence on the likelihood of separation. Even after individual assessm
ents are taken into account however, demographic factors such as age a
t marriage, marital duration, prior experience in a disrupted marriage
