ICE data codebook

We provide a codebook for the main ICE data tables and fields. The codebook is a work in progress; there are many things we do not understand in the data, and some of our educated guesses here may be mistaken. We will continue to update the codebook as we learn more, and we welcome feedback and corrections.

Tables

We describe the main ICE data tables below.

Fields (variables) in latest data release

We describe the fields (a.k.a. variables or columns) in the latest ICE data release below. The table includes the name of each field, a description, and the type of data in the field (e.g., string, numeric, date). Expanding a row will show an indicator for whether the field is available in each table and the proportion missing.

Fields (variables) in previous data releases

We also provide a table of fields (a.k.a. variables or columns) that were available in previous ICE data releases but are not included in the most recent data. This table includes the name of each field, a description, and the type of data in the field (e.g., string, numeric, date).
