- birth_state: Birth state (region) of the interviewee, filled only when speaker_type = 'R';
- birth_country: Birth country of the speaker;
- age: Age of the interviewee, calculated with recording_year minus year of birth, filled only when speaker_type = 'R';
- recording_year: The year when the audio was recorded;
