Local context: Singapore parameters
Singapore's rules are unusually flat and predictable, and Statistics reflects that structure directly.
Key local facts
- Currency: Singapore dollars, S$1,234.56. GST is currently 9% and shown inclusive on most consumer prices.
- Income tax: Progressive resident rates from 0% up to 24%, with no capital gains tax and no inheritance tax.
- CPF: Mandatory CPF contributions from both employer and employee, split across Ordinary, Special and MediSave accounts by age band.
- Units: Metric — km, kg, °C, litres — with residential space quoted in square feet despite the metric norm.
- Power: 230 V / 50 Hz with Type G plugs, and installations follow SS 638.
Local examples
- Example — CBD: An employee in the CBD uses Statistics to separate CPF from take-home pay before budgeting.
- Example — HDB resale: A buyer checks an HDB resale figure with Statistics, keeping stamp duty as a separate calculation.
Every figure above applies to Singapore specifically and is reviewed when the rules change.
