Hi all,

I would like to find education attainment information by zip-code nationwide via American Community Survey.

Since I am super new to the data, I wish to gain your perspective for two specific questions.

Using year 2016 as an example, the data file I download is "B15003 EDUCATIONAL ATTAINMENT".

B15003: Census Bureau Table

(1) How do I calculate the % of high school completion or higher correctly? There are something like estimate or margin values...

(2) In the file, it has ZCTA information. Should I use the below zipcode and ZCTA crosswork to get the the education attainment by zipcode?

Many thanks for your suggestion in advance.

For how to compute the MoE (Margin of Error) for a %. Note these formulas are approximate and need some adjustment near 0 or 100 %
