a
In 2012, survey stopped collecting data for this item.
b
Variable added to the Doctorate Records File in 2014.
c
Methodology reports prior to 2014 reported BAEYEAR as CEYEAR.
d
Variable has low response rate because although all respondents are considered eligible to provide data for item, only some are able to do so.

h
Methodology reports prior to 2014 reported PHDEYEAR as PHDENTRY.
i

j

m
Item appeared on survey form for the first time in 2007 (see "NOTES").
NOTES: Response rate is the percentage of cases providing data on an item divided by the universe of doctorate recipients eligible to answer that item. For most items, the full universe of doctorate recipients establishes the universe of
eligible respondents. However, the number of items that appeared on the survey form for the first time were restricted to a subset of the full universe because a high percentage of respondents submitted data on earlier versions of the
survey form. Response rates for these variables are not reported in the year that the item appeared on the survey but are reported in subsequent years, when the item became available to the entire respondent universe.
