How we compute prices and statistics
As of August 14, 2026, every number on the site comes from one place, the daily snapshot of the database. Today's holds 2,394 active listings and 12 sources; +520 listings arrived in the last 24 hours. Below is what exactly is measured, what it equals today, and where the limits of these figures are.
What we measure
Each row is a figure you will meet on the city pages and on listing cards. A figure missing from the snapshot has no row: this table carries no dashes and no default values.
| Figure | Today | What it means |
|---|---|---|
| Live listings | 2,394 | How many listings are available on the snapshot date. |
| New in 24 hours | 520 | How many listings arrived since the previous snapshot. |
| Sample size | 2,394 | How many listings the median and the percentiles are computed from. |
| Sources | 12 | How many source families supplied listings. |
| Median per month | $463 | The price exactly in the middle of the list: half is cheaper, half is dearer. |
| Half of the market | $269–962 | The band between the 25th and the 75th percentile: a quarter below, a quarter above. |
| Price per square metre | $8 | The median across listings that state the floor area. |
| Posted by agents | 38% | What share of listings comes from agents rather than owners. |
| Rate, ₫ per $1 | 25,990 | The catalogue rate used to convert prices into dollars. |
| Snapshot date | August 14, 2026 | The day every number in this table was taken. |
The daily snapshot
Once a day the whole database is photographed: how many listings are live, how many arrived within the day, what their prices are. Every page then reads its numbers from that photograph instead of counting on its own.
- Every number carries a date. The snapshot day always stands next to the figure: a number without a date turns into a lie within a week.
- The sample is stated. We say how many listings the median is computed from. A median over twelve cards and one over two thousand are different things.
- Counters add up, medians do not. The live listings of two districts can be added together, their medians cannot: the mean of two medians is not a median. Where adding is impossible, the number is simply not shown.
Why the median, not the mean
A single villa at twelve thousand dollars lifts the mean of a district so far that it stops describing any real home at all. The median — the price exactly in the middle of the list — survives such outliers. Next to it we show the band: a quarter of listings sit below the lower bound, a quarter above the upper one, and half of the market lies between them.
The rate and the conversion
Sources state prices in dong and in every possible notation. A card shows dollars at the catalogue rate and keeps the original price so it can be checked against the source. The rate is the same across the whole site: converting separately in each block would show two different numbers for one and the same flat.
The limits of our numbers
Worth knowing before you cite them.
- These are asking prices, not deals. We see what is being asked, not what was finally agreed: haggling on the spot is routine here.
- Floor area is not always known. Price per square metre is computed only across listings that state the area, so its sample is smaller than the whole.
- Geography comes from a register. The city and the district are resolved against the official administrative register; a listing whose source named neither does not enter district-level figures.
- The snapshot is our database, not the whole market. We count what we have collected. A site we do not crawl is not reflected in the figures — the make-up of sources is open on its own page.
Where to go next
Data as of August 14, 2026. Sample: 2,394 active listings across 12 sources; prices are converted to dollars at the catalogue rate, and duplicates across boards are merged into a single card.
