Methodology for Developing a Thailand Price Index
Building a reliable index involves several critical steps:
1. Data Collection
Gather comprehensive data from multiple sources:
- Property Listings: Real estate portals, developer listings, and agents.
- Transaction Records: Official government registry data, Land Department reports.
- Market Surveys: Expert opinions, broker assessments, and developer forecasts.
- Legal and Tax Documentation: Price disclosures from legal checks and audit reports.
Tip: Cross-validate data sources to increase accuracy and reduce bias.
2. Data Cleaning and Validation
- Remove duplicate entries.

3. Categorization and Segmentation
Segment properties based on:
- Region: Bangkok, Phuket, Pattaya, Chiang Mai, etc.
- Property Type: Condominiums, houses, commercial units.
- Price Range: Budget, mid-range, luxury.
This segmentation enhances the index’s relevance for specific market tiers.
4. Weighting and Aggregation
- Assign weights based on transaction volume or market significance.
- Use statistical techniques (e.g., weighted averages) to aggregate data into a composite index.
5. Index Calculation
Employ well-established statistical methods like:
| Methodology | Description | Use Case |
| Laspeyres Index | Uses base period quantities with current prices | Comparing over time with fixed quantities |
| Paasche Index | Uses current period quantities | Updating base to reflect recent changes |
| Fisher Index | Geometric mean of Laspeyres and Paasche | Reduces bias in index measurement |
Most real estate indices utilize a modified Laspeyres or Fisher approach for balanced accuracy.
6. Continuous Monitoring and Updating
