primary
Data that you yourself have collected (or commissioned their collection), rather than obtained from some other source.
Primary would be the first of whatever you're talking about, and secondary would be the second or the once-removed whatever it is. For example, a primary source of research would be something like a diary or letter, which would be a first-line information source - a secondary source would be a textbook reporting about what the person described in the letter or diary.
Primary data can be slow to acumulate, and is also relatively expensive. Secondary data is faster and often free of charge, but you must ensure that the source from which you take your data is reliable.
