a
Estimates are adjusted to age 30 and are weighted using the NLSY custom weights for the whole study period (1988-2016).
b
Represents the highest tertile of precarious employment. Tertiles were generated based on the pooled sample across all years (N=101,290 observations).
c
Reference group for statistical testing. We used t-tests (average PES) and chi-squared tests (prevalence of PE) to test for differences between the reference and other group.
d
P<0.05
