# Mobility Updates


### Last meeting

#### Content

- Binscatter middle school completion and co-residence by age to find the ages at which we can observe education without too much coresidence bias.

#### Stylistics Changes

- Add spaces `blah>=5` &rarr; `blah >= 5`
- Use global `$tmp` instead of Stata tempfile: `save $tmp/fam, replace`
- Careful merges: `, assert(match using)` 
- Use `inlist`: `educd==2 | educd==11 | educd==12`  &rarr; `inlist(educd, 2, 11, 12)`
- Ensure not missing: `& !mi(hgc)`

#### MS Completion

Binscatters of middle school completion (attains at least 8th grade) and co-residence by age in all censuses:

Based on those plots, I limit the census samples to only ages 17-18. This is what middle school completion across all samples then looks like:

I make the NLSY survey samples similar to census samples (top coded coresiders of similar birth cohort years):

#### 9th Grade and HS Completion

I make similar binscatters for 9th grade and high school completion in the later censuses (1950-1990).

Ninth grade completion by census year:

### What's next

- [ ] Pull earlier years of PSID so we can measure education at appropriate ages.
