Methodology
The index represents the employment of software developers each month relative to January 2018. To identify software developers in the ADP sample, we independently matched two criteria, job titles and O*NET occupation codes, followed by review and filtering of the results. A set of employees was identified by querying a set of keywords present in known software developer job titles (such as software engineer, C++ developer, stack developer) and querying O*NET occupation codes for software developers (15-1252.00, 15-1253.00, 15-1254.00 and 15-1221.00). Combined data resulting from these queries was manually reviewed to weed out any job titles captured erroneously. Because the list of resulting job titles was quite long, a rule of thumb was applied to job titles that occur fewer than 2,500 times. These had to contain the key words “software” or “developer” to be included in the sample. |
