variable endings: _0, _1, etc.
Variable names in the longitudinal dataset are similar between the Baseline, First Follow-Up, Second Follow-Up, and Third Follow-Up Surveys. With the exception of MPRID and the credit risk variables, all variables in the data file will have a suffix that corresponds to a round of data collection. Baseline variables contain an _0 suffix, First Follow-Up variables contain an _1 suffix, Second Follow-Up variables contain an _2 suffix, and Third Follow-Up variables contain an _3 suffix.
*** Please note that these variable names differ from the dataset released in 2008 in which Baseline variables did not have a suffix, First Follow-Up data had an _f suffix, and the Second Follow-Up data had an _s suffix. The new suffixes ( _0- _3) should allow easier incorporation of each new year of data as it becomes available ( _4 - _7).
