and not used in front ends directly.

contexts can only be used with the country lookup alone.

Current lists include:
ageGroup, companySize, country, educationLevel, employmentStatus, ethnicity, gender, householdIncome, industries, jobTitles, marketType, researchMethodology, typeofResearch, skills, topics

note: industries, jobTitles, skills, topics return a LOT of data and
can be very slow to return
