Family as a basic social unit- Stats

Some stats from http://www.stepfamilies.info/stepfamily-fact-sheet.php

Sadly they decided to discontinue providing estimates of marriage, divorce, and remarriage except for those that are available from current census. Thus, many of the following current estimates were derived from the 1990 census and earlier data sources. This is for the US, but I would be interested in plotting say how GDP and Family Unit size changes— across countries

Current estimates from 1988-1990 suggest:

92% of all men and women marry by age 50
43% of first marriages will end in divorce within 15 years
25% of all men and women report being marriage two or more times by age 50
In 2004, 42% of all marriages were remarriages for at least one partner
Of those who get divorced, 75% will remarry (65% bring children from a previous union)
60% of those who get remarried redivorce
15% of remarriages will end in divorce within 3 years, 25% within 5 years, 39% within 10 years
The average length of first and re- marriages that end in divorce is about 8 years
The average time between first divorce and remarriage is about 3.5 years
54% of women will remarry within 5 years of first divorce and 75% within 10 years
50% of men who remarry after first divorce do so within 3-4 years
Having low income and living in poor neighborhoods are associated with a lower chance of remarriage
Younger adults are more likely to remarry than older ones
Whites and Latinos are more likely to remarry than African Americans
After 5 years of divorce Whites are most likely to remarry (58%), followed by Latinos (44%) and African Americans (32%)
These proportions show a marked downward trend when compared to national samples in 1976, which indicated the probability of remarriage within 5 years of divorce was 73% for Whites and nearly 50% for African Americans
Estimates suggest that by the time they are 18, anywhere from 1/3 to 1/2 will have been part of a stepfamily

In addition while billions are being spent on data software , how can we cut down the cost of collecting Census data using newer technologies ( than those paper forms!!)
