Percentages are based on responses and do not incorporate missing data.
Multiple responses for occupation causes the sum for the “percentage of cases” to be >100. “Unemployed” refers to those without paid work who are currently seeking employment. No paid work includes those who are homemakers, caring for family, volunteering, attending school, disabled, or on maternity leave.
