StatisticsElaboration/Remarks
O-Sum-cy-mq-v-7-ab=
B's denote CHANGE in happiness following CHANGE in 
age in individuals (fixed effects)
O-Sum-cy-mq-v-7-ab=+.06 p < .001
Interpretation: most Ss got a bit happier between 
age 18 and 34
O-Sum-cy-mq-v-7-ab=+.01 ns
B controlled for private life course transitions:
- leaving parental home
- living together/marriage first partner
- divorce from first partner
- living together/marriage second partner
- having first child
O-Sum-cy-mq-v-7-ab=-.01 ns
B controlled for public life course transitions:
- first paid job
- no job
O-Sum-cy-mq-v-7-ab=-.04 ns
additional control for years since transition:
- first paid job
- no job
- leaving parental home
- living together/marriage first partner
- divorce from first partner
- living together/marriage second partner
- having first child
O-Sum-cy-mq-v-7-ab=-.08 p < .05
additional control for years since transition 
squared:
- first paid job
- no job
- leaving parental home
- living together/marriage first partner
- divorce from first partner
- living together/marriage second partner
- having first child

Interpretation: Ss who did not experience life 
transitions over this period became less happy
Unaffected by squaring the above years of 
transition variables

Unaffected by gender

B's indicate change within individuals over this 
12 year period (fixed effect)


Appendix 1: Happiness measures used
CodeFull Text
O-Sum-cy-mq-v-7-aSelfreport on four questions:

Using the 1-7 scale below, indicate how much each of the following statements applies for you in the last 18 months.
A In most ways my life is close to ideal
B The conditions of my life are excellent
C I am satisfied with my life
D So far, I have gotten the important things I want in life

Answers rated:
7 applies completely
6 apllies
5 apllies slightly
4 neither applies nor does not apply
3 slightly not applicable
2 not applicable
1 applies not at all

Computation: A+B+C+D divided by 4

Name: Shortened Diener's Satisfaction with Life Scale (SWLS), last years version
(In the original scale item 5 reads: 'If I could live my life over, I would change nothing'. This item is left out in this selection because a positive answer to this question does not necessarily mean that the respondent doesn't like the life he/she actually lives.)

SymbolExplanation
bREGRESSION COEFFICIENT (non-standardized) by LEAST SQUARES (OLS)
Type: test statistic
Measurement level: Correlate: metric, Happiness: metric
Theoretical range: unlimited

Meaning:
b > 0 A higher correlate level corresponds with a higher happiness rating on average.
B < 0 A higher correlate level corresponds with a lower happiness rating on average.
B = 0 Not any correlation with the relevant correlate.
