Methodological Considerations
Understanding data sources and analytical approaches
Data Collection Methods
Hong Kong's labor statistics primarily derive from household surveys (particularly the General Household Survey), establishment surveys, and administrative records. Each source has distinct strengths and limitations. Household surveys capture comprehensive demographic information and employment characteristics but rely on sample-based estimation. Establishment surveys provide detailed industry-level data but may undercount informal employment.
Statistical Definitions
Understanding statistical definitions is crucial for accurate interpretation. The "employed" category includes persons aged 15 and over who work for pay or profit, or who perform unpaid work in family businesses. "Unemployed" refers to persons without employment who have actively sought work in a specified reference period. These internationally-aligned definitions facilitate comparative analysis.
Seasonal Adjustment
Many labor statistics undergo seasonal adjustment to remove regular patterns related to calendar effects, weather, and institutional factors. Seasonally adjusted data better reveal underlying trends but should be interpreted alongside unadjusted figures to understand total labor market dynamics.
Data Limitations
All labor statistics have inherent limitations. Survey data contain sampling errors; administrative data may exclude certain worker categories; and rapid structural changes can affect comparability over time. Critical analysis requires awareness of these constraints and appropriate contextualization of findings.
