Week 02 Lab: Anyone figure out what `globd` or `globg` mean?

[cenuno]

I couldn't find either variable in the codebook nor had success using Google to find these variables.

If no one finds the answer feel free to move forward without supplying definitions for these columns.

[lecy]

These are categorical variables describing the racial composition of the neighborhoods (tracts).

GlobD10	GlobG10
bw	White Black
wha	Dual immig
bw	White Black
wha	Dual immig
bw	White Black
wha	Dual immig
bw	White Black
wha	Dual immig
wba	Semi global
wh	Single immig
bw	White Black
wha	Dual immig
bw	White Black

They were included in the raw files, but I don't recall seeing documentation anywhere. So yes, please create your own descriptor or just ignore them.

There are a handful of variables that were not included in the codebook provided by the group that created the data. Bad practice, but also not uncommon if a project evolves over time.

@lecy thank you for the context and explanation! This only prompts more questions for me, particularly:

• what the demographic composition of the tract is needed to be classified as GlobG10='Semi global'; and
• how is "dual" identified in 'dual immig'? Why not triple or quadruple?

For now I'll put these in my back pocket as something to explore once we move onto data exploration next week. Appreciate you shining a light on these variables!

I had the same questions. I'm sure there was some coherent methodology behind the creation of the variables, but I have no idea what it was.
