Four numbers to start: we're tracking 1,129,012 live used-car listings across 73 regions and 1,376 sources right now. Sweden — population roughly 10.5 million — contributes 28,015 of them. Brazil, population roughly 203 million, contributes 37,591. The United States, population roughly 335 million, contributes 48,126.
Sit with that for a second. Brazil has nineteen times the people Sweden does and produced about 1.3x the listings. The U.S. has thirty-two times Sweden's population and produced 1.7x the listings. If listing volume tracked population, the U.S. number should be somewhere north of 900,000. It's 48,126.
That's not a data-collection failure on our end — we crawl US sites as hard as anywhere. It's telling you something real about where used cars actually get bought and sold.
The per-capita math nobody runs
Divide population by listing count and you get a rough "people per listing" figure — not a precise measure of market size, but a decent proxy for how much of a country's used-car activity happens somewhere a crawler can see it.
UAE sits at the far end, around 125 people per listing — a market we've written about before, small, cash-rich, and almost entirely funneled through a handful of dominant platforms. But look at the cluster right behind it: Portugal, Czech Republic, Sweden, Belgium — all landing between roughly 300 and 380 people per listing, despite having almost nothing else in common geographically or economically. Then there's a cliff. France, South Korea, Poland, and Canada sit in the 900-1,200 range. Japan drifts out to about 2,000. And then Brazil and the U.S. fall off the chart entirely, past 5,000 and nearly 7,000 people per listing respectively.
Why the giants look empty
The intuitive explanation — "Americans and Brazilians just buy fewer used cars" — is wrong. The U.S. moves something like 36 million used vehicles a year, more than any market on earth by volume. Brazil's used-car market is one of the largest in Latin America. These aren't small markets. They're markets where the listing itself is scattered.
In Sweden, Blocket is close to the entire classifieds market in one place. In the Czech Republic, Sauto and TipCars cover most of what's for sale nationally. In Belgium, 2ememain and AutoScout24 do the same. Crawl the two or three sites that matter and you've captured a large fraction of the country's actual used-car inventory — which is exactly why small, wealthy, digitally consolidated markets produce listing counts that look disproportionate to their population. They aren't disproportionate. They're just visible.
The U.S. has no single site that is the market. Inventory is split across Cars.com, CarGurus, AutoTrader, Facebook Marketplace, dealer-only franchise sites by state, and a long tail of regional classifieds — plus a huge slice of private-party and dealer-lot transactions that never touch an aggregator site at all. Brazil runs on OLX plus a fragmented mix of regional and dealer-direct channels, with a meaningful share of used-car commerce still happening through word of mouth, consignment lots, and informal networks that no listing site, let alone a crawler, ever sees.
So the 48,126 US listings and 37,591 Brazil listings in our database aren't the size of those markets. They're the size of the slice of those markets that happens to be digitized, aggregated, and crawlable — and that slice is genuinely smaller, relative to the country, than it is in Stockholm or Prague.
What this means if you're shopping in one of these markets
| Market type | People per listing | What it means for you |
|---|---|---|
| Consolidated small market (Sweden, Czech Republic, Belgium, Portugal) | ~300-400 | A handful of searches covers most of what's actually for sale |
| Mid-fragmented (France, South Korea, Poland, Canada) | ~900-1,200 | Expect to check 2-3 major sites to see the real market |
| Large, fragmented (Japan) | ~2,000 | Significant volume moves through dealer-only or auction channels outside public listings |
| Giant, decentralized (Brazil, USA) | 5,000+ | Any single site — ours included — is a sample of the market, not the market |
That last row is the one worth internalizing if you're car-shopping in the U.S. or Brazil. A below-market flag or a price estimate built from a sample this thin isn't wrong, but it's working with less of the true market than the same model would have in Belgium. We correct for that with region-cohort pricing rather than one blended curve, precisely because the "visible" market in a fragmented country isn't a random sample — it skews toward whatever happens to list online, which tends to be dealer inventory more than private-party deals. In a market like Sweden's, what you see online is close enough to what you'd see driving around. In the U.S., it's a window, not the whole house.
