How many speak Mandarin, Cantonese and Shanghainese?

Mandarin, as a first language, is spoken by about 990 million people — more native speakers than any other language on Earth. Count everyone who can use Standard Chinese, the taught national standard built on Mandarin, and China's own figure passes 80% of the country: well over a billion people, a different and much bigger number than the first. Cantonese, as the Yue branch it belongs to, has around 85 million speakers; narrowed to Cantonese itself it's closer to 80 million. Shanghainese has no census of its own at all, only estimates in the tens of millions, and — measured several different ways by several different surveys — a clear generational decline. None of these is one question with one answer, and this page is about why.

Why the same language gets three different numbers

Every count of a Chinese language is really answering one of three distinct questions: what did you grow up speaking (native language), what can you manage (ability), or what do you actually use day to day (usual language). Hong Kong's census is the clearest case of this because it asks its population all three in the same survey, and gets three different numbers back. Keep that distinction in mind below — it's the reason a "decline" in one measure can sit next to stability in another for the very same people.

Mandarin: a billion-person gap between two definitions

The 990 million figure is for the Mandarin dialect group as a mother tongue — the language of most of northern and south-western China, from Yunnan to Heilongjiang. It is not the same as asking how many people in China can function in Standard Chinese, the standardised register built on Mandarin's grammar and Beijing's pronunciation and taught in every school.

That second number has moved faster than almost any language statistic in the world. A 2007 Ministry of Education survey put it at 53.06%. By 2020 it had passed 80% — widely reported, including by Chinese state media, as precisely 80.72% — and the government's stated target is 85% by 2025 and "virtually the entire country" by 2035. Two decades turned roughly half of China's population into speakers of a standard they didn't grow up with; nothing comparable has happened to a language at this scale in peacetime. The distinction between "Mandarin" the dialect and "Standard Chinese" the taught register — and how every other branch of Chinese fits around them — is set out properly in the Chinese languages, by number of speakers.

Cantonese: the same census, three different questions

"Cantonese" itself is layered. The Yue branch of Chinese, which Cantonese belongs to, has about 85 million speakers; Cantonese narrowly defined — the Guangzhou-Hong Kong prestige form people usually mean by the word — is closer to 80 million. In Guangdong, the province Cantonese comes from, Yue speakers are a minority of their own home: roughly 47% of the province's population speaks a Yue variety natively, with Hakka and Min speakers making up most of the rest.

Hong Kong is where the three-questions problem is easiest to see, because its 2021 census asked each one. As a usual language — what residents actually speak day to day — Cantonese was at 90.6%, down slightly from 91.5% in 2011. As an ability — can you speak it at all — it was at 96.0%, far higher than the usual-language figure because it also counts people who speak something else at home but can hold a conversation in Cantonese. And ability in Putonghua rose over the same decade, from 49.5% to 56.5%. Three figures, one population, one census — and together they describe rising bilingualism rather than Cantonese being replaced. Mandarin vs Cantonese compares the two languages feature by feature if you want the rest of that picture.

Across the border in mainland Guangdong, the pressure runs the other way, and in 2010 it produced a rare public test of feeling: a proposal to increase Mandarin programming on Guangzhou Television drew 79.5% opposition in a 30,000-person survey, then a roughly 10,000-strong rally and a second gathering where police detained about twenty people, including several journalists. The station kept its Cantonese programming. The wider pattern of which Chinese languages are actually shrinking, and which only look like they are, is on are Chinese topolects dying.

Overseas, Cantonese has held its ground in absolute numbers while losing relative ground to Mandarin among new arrivals. Canada's 2016 census counted about 565,000 native Cantonese speakers (44% born in Hong Kong, 27% in Guangdong, 18% in Canada itself); the United States counted roughly 459,000 people speaking it at home in 2009; about 300,000 people in the United Kingdom give it as their first language. Australia shows the shift most clearly: between the 2011 and 2016 censuses, Cantonese speakers grew modestly from 263,673 to 280,943, while Mandarin speakers nearly doubled, from 336,410 to 596,711 — Mandarin overtaking Cantonese as the Chinese Australian community's biggest language not because Cantonese fell, but because Mandarin-speaking immigration grew so much faster.

Shanghainese: the one nobody has properly counted

There has never been a census question asked specifically about Shanghainese. The number usually quoted, 15.86 million, is a 2012 estimate of the population of the region where it's spoken — not a survey of who actually speaks it. The Wu Chinese branch it belongs to is larger and better measured: Ethnologue's count has moved from 81 million in a 2019 estimate to 83 million in 2021, which is itself a reminder that even the "solid" numbers here are periodically revised estimates, not a headcount.

Shanghai's own demographics make the local number especially slippery. At the November 2020 census the city had 24,870,895 residents, of whom 10,479,652 — 42.1% — had household registration elsewhere and had moved there. A city where four in ten residents grew up speaking something else entirely will always report a lower Shanghainese-speaking share than a count of people actually born there would.

Within that complication, every survey that has asked the question points the same way. In 2010, a study of Shanghai primary schoolers found 62.6% used Mandarin as their first language at home against 17.3% for Shanghainese, and only 10.2% said they'd rather study Shanghainese than Mandarin. A 2013 telephone survey of residents aged 13 and over put the share who could speak at least some Shanghainese at 81.4% — but the Shanghai-born 13-to-20-year-olds in that same survey rated their own ability lower than every other age group did. Street surveys in 2016 and 2017 found 96% of Shanghai-born adults fluent against just 70% of those under 25. And the most recent figure, from a 2021 survey, is the starkest: about a third of under-30s said they can only understand Shanghainese, not speak it, 15.22% of under-18s said they would never use it at all, and 8.7% of under-18s said they can't even understand it. Put the generational and the city-wide numbers side by side and the measurement point above becomes concrete: across Shanghai's whole population, including the 42% who weren't born there, roughly half can hold a conversation in Shanghainese and about another quarter can follow one without speaking it — a very different number from the 96% fluency among people actually born in the city. Both are true; they're counting different groups. The fuller story of why, and what the city is doing about it, is on is Shanghainese dying and what language is spoken in Shanghai.

The three, side by side

So which number is "the" number?

There isn't one, and a source that gives you a single figure for any of these three languages without saying what it's counting is skipping the hardest and most interesting part of the question. Mandarin's 990 million native speakers and its billion-plus Standard Chinese speakers answer different questions about the same language family. Hong Kong's census shows a single population can be simultaneously stable (by ability) and shifting (by usual language). And Shanghainese shows how much the answer depends on who's in the room when you ask — a city of migrants will always undercount the language of the people who were born there.

Learning any of these three starts with hearing them spoken correctly. The Mandarin course and the Shanghainese course — Verbavia (our own course) — are both free on the web in any browser, including on a phone, with every word's audio recorded rather than guessed at, which matters most for exactly the language on this page where getting it wrong is easiest: Mandarin and Shanghainese share a writing system but not a sound.
