推計 en 30 segundos
- 推計 (suikei) means 'estimation' based on statistical data and logical inference.
- It is a formal word used in business, economics, and government reports.
- Commonly used for population projections or market size calculations.
- It focuses on the mathematical process of finding unknown values from known ones.
The Japanese word 推計 (suikei) is a sophisticated noun and suru-verb that translates primarily to 'estimation' or 'statistical projection.' In the realm of Japanese linguistics, it sits at the intersection of data science and logical inference. Unlike a simple guess or a casual estimate, suikei implies a rigorous process where existing, known data points are used to calculate values that are currently unknown or to project values into the future. It is the language of economists, demographers, and policy makers who must navigate the complexities of populations that are too large to count individually or events that have not yet occurred.
- Etymological Breakdown
- The first kanji, 推 (sui), means to 'push' or 'infer.' It suggests moving from a known point toward an unknown conclusion. The second kanji, 計 (kei), means to 'measure' or 'calculate.' Together, they form the concept of 'calculating through inference.'
You will most frequently encounter suikei in formal contexts, particularly in government white papers (白書) or news reports regarding population trends. For instance, when the Japanese government discusses the 'Estimated Future Population' (将来推計人口), they are not merely guessing; they are applying complex mathematical models to current census data to predict what the population will look like in 2050. This word carries a weight of authority and scientific methodology that words like yoso (prediction) or kan (intuition) lack.
最新の国勢調査に基づき、将来の労働力人口を推計した結果、大幅な減少が見込まれることがわかった。(Based on the latest census, the result of estimating the future labor population revealed that a significant decrease is expected.)
Furthermore, 推計 is essential when dealing with 'hard-to-count' groups. For example, the number of people infected with a virus in a specific region is often a suikei because it is impossible to test every single citizen. By testing a representative sample and applying statistical weights, experts arrive at a suikei-chi (estimated value). This makes the word indispensable in public health and sociology. It bridges the gap between the concrete reality we can see and the broader reality we can only understand through math.
- Domain: Economics
- In economics, 推計 is used for GDP projections or market size evaluations where the total transaction volume isn't publicly disclosed by every company.
この市場の潜在的な規模は、年間5000億円に達すると推計されています。(The potential size of this market is estimated to reach 500 billion yen per year.)
Using 推計 (suikei) correctly requires an understanding of its grammatical flexibility. As a noun, it often functions as the subject or object of a sentence, frequently paired with the particle ni yoru (based on) or wo dasu (to produce/calculate). As a suru-verb, suikei suru describes the act of performing the calculation. Because of its formal nature, it is almost always used in the passive voice in news reports—suikei sareru (it is estimated that...).
- Common Structure: [Source] + に基づく + [推計]
- This structure is used to indicate the data source. For example: '統計データに基づく推計' (Estimation based on statistical data).
One of the key nuances of 推計 is that it focuses on the calculation process. If you are simply guessing who will win a soccer match, you cannot use 推計. However, if you have a database of player stats, weather conditions, and historical win rates, and you run that through an algorithm to find a probability, you are performing a suikei. In a sentence, this looks like: '過去の対戦成績から勝率を推計する' (To estimate the win rate from past match results).
政府は、来年度の税収を約60兆円と推計した。(The government estimated next year's tax revenue to be approximately 60 trillion yen.)
When talking about the results of the estimation, you often use the word 推計値 (suikei-chi), which means 'estimated value.' This is a technical term used to distinguish between the 'actual value' (実績値 - jisseki-chi) and the calculated one. For example: '推計値と実績値の間に乖離が生じた' (A discrepancy arose between the estimated value and the actual value). This distinction is vital in professional writing to maintain transparency about where data comes from.
この地域の野生動物の個体数は、1000頭前後と推計されています。(The population of wild animals in this region is estimated to be around 1,000.)
If you turn on the NHK news or pick up a copy of the Nikkei Shimbun, you will hear 推計 (suikei) within minutes. It is a staple of the Japanese media landscape, particularly when reporting on the 'society of fewer children and aging population' (少子高齢化社会). Because Japan is undergoing unprecedented demographic shifts, the government regularly releases suikei reports to prepare the public for future changes in social security and infrastructure needs.
- News Context: NHK Reporting
- '厚生労働省の推計によれば...' (According to the estimation by the Ministry of Health, Labour and Welfare...). This is the most common way to introduce a news segment on social trends.
Another common venue for this word is in environmental science and disaster prevention. After an earthquake or a flood, scientists provide a suikei of the damage or the number of people displaced. Similarly, in the fight against climate change, researchers use suikei to model how much sea levels will rise or how much CO2 emissions need to be cut. In these contexts, 推計 represents a call to action based on scientific probability rather than a mere guess.
震災による経済的損失は、数十兆円に上ると推計された。(The economic loss due to the earthquake was estimated to amount to tens of trillions of yen.)
In the corporate world, 推計 appears during quarterly earnings reports and strategic planning sessions. CEOs use it to talk about 'Market Share Estimation' (市場シェアの推計) or 'Customer Lifetime Value Estimation.' It signals to investors that the company is using data-driven methodologies to plan its future. If a manager says 'My suikei shows we need more staff,' they are implying they have analyzed the workflow data, not just that they feel tired.
このアプリの利用者数は、年末までに100万人に達すると推計している。(We estimate that the number of users of this app will reach one million by the end of the year.)
The most frequent mistake learners make with 推計 (suikei) is using it in place of more casual words like yosou (prediction) or mitsumori (estimate/quote). While they all involve looking into the unknown, their registers and nuances are vastly different. Using 推計 to guess what your friend wants for dinner sounds unnervingly robotic and statistically over-engineered.
- Mistake: Confusing 推計 with 見積もり (Mitsumori)
- A mitsumori is a quote or a price estimate for a specific service (like a car repair). 推計 is for general statistical trends. You don't 'suikei' the cost of a wedding; you 'mitsumori' it.
Another common error is confusing 推計 with 推定 (suitei). While very similar, suitei is often used for 'presumption' or 'assumption' in a legal or scientific sense (e.g., 'presumed dead' is 推定死亡). 推計 is strictly about the calculation aspect. If you are trying to determine a specific number through a formula, 推計 is the better choice. If you are making a logical assumption based on circumstantial evidence, 推定 is usually preferred.
❌ 明日の天気を推計する。
✅ 明日の天気を予報する。(Weather is yohou, not suikei.)
Furthermore, learners often forget that 推計 requires a base of data. You cannot suikei something out of thin air. If there is no mention of a dataset, survey, or historical record, the word feels out of place. It is a word that demands a 'why' and 'how'—specifically a mathematical 'how.' Using it for a gut feeling will make your Japanese sound unnatural and overly formal in the wrong way.
❌ 彼の気持ちを推計する。
✅ 彼の気持ちを推測する。(Feelings are suisoku, not suikei.)
To master 推計 (suikei), you must understand its neighbors in the semantic field of 'estimating.' The Japanese language has many words for this, each with a specific niche. Choosing the wrong one can change the tone of your sentence from 'expert analyst' to 'clueless gambler.'
- 推定 (Suitei) - Presumption
- Used when you assume something to be true based on evidence. Common in science and law. Example: '推定無罪' (Presumption of innocence).
- 予測 (Yosoku) - Prediction
- Focuses on future events. It is more general than suikei and can include qualitative predictions. Example: '景気の予測' (Economic outlook prediction).
- 見積もり (Mitsumori) - Quote/Estimate
- Specific to costs, time, or labor required for a task. Example: '修理の見積もり' (Repair estimate).
Then there is 推測 (suisoku), which is 'conjecture.' This is much more subjective than 推計. If you see someone crying and think they are sad, that is suisoku. You are using your intuition and observation. 推計, however, would involve looking at the volume of their tears, the decibel level of their sobs, and comparing it to a database of human emotional responses to calculate a 'sadness index.' This highlights how 推計 is tied to numerical data.
専門家は、この地域の人口が20年後に半分になると推計しているが、市民は楽観的な予測を立てている。(Experts estimate (statistically) the population will halve in 20 years, but citizens hold optimistic predictions.)
Finally, consider 算出 (sanshutsu) which means 'calculation.' While 推計 involves inference, sanshutsu is the straightforward math of adding things up. If you have all the numbers and just need the total, use sanshutsu. If you are missing pieces of the puzzle and need to fill them in logically, use 推計. Understanding these boundaries will make your Japanese precise and professional.
How Formal Is It?
Dato curioso
The kanji 推 (sui) is also used in the word for 'mystery novel' (推理小説 - suiri shousetsu), because both involve inferring the unknown from clues!
Guía de pronunciación
- Pronouncing 'sui' as 'swi' (like swim). It should be two distinct sounds: su-i.
- Shortening the 'kei' to 'ke'. It should be a long vowel sound.
- Misplacing the pitch accent on the first syllable.
- Confusing 'suikei' with 'suike' (a different word).
- Over-emphasizing the 'i' in 'sui'.
Nivel de dificultad
Kanji are common but the word is formal and appears in complex contexts.
Requires knowledge of formal sentence structures like passive voice.
Pronunciation is easy, but finding the right context to use it is tricky.
Often heard in fast-paced news or technical presentations.

Consejos
Use for Big Data
Whenever you are dealing with millions of people or trillions of yen, 'suikei' is the most appropriate word to use in a professional setting.
The Passive Voice
In news and reports, 'suikei sareru' (is estimated) is much more common than 'suikei suru' (to estimate). It makes the statement sound more objective.
Suikei vs Suitei
Remember: Suikei = Numbers/Math. Suitei = Facts/Assumptions. If you are calculating a total, go with Suikei.
Impress Your Boss
Using 'suikei' in a presentation shows that you have a data-driven mindset. It sounds much more professional than saying 'I think the market is big.'
Watch for Headlines
Look for the kanji 推計 in newspapers. It will almost always be followed by a large number and the particle 'と'.
Learn the Opposites
Pair 'suikei' with 'jisseki' (actual result) in your mind. This contrast is very common in business reporting.
Prerequisites First
When writing a sentence with 'suikei,' always try to include the basis of the estimate (e.g., 'data ni motoduite') to sound more natural.
Pitch Matters
Keep the pitch flat. If you drop the pitch on 'kei,' it might sound like you are starting a new word.
Demographic Context
Understand that in Japan, this word is often linked to the 'aging society' discussion. Knowing this context helps you understand the 'mood' of the word.
Kanji Clue
The 'push' (推) kanji is your clue that we are pushing our knowledge into the unknown. This helps distinguish it from simple 'calculation' (計).
Memorízalo
Mnemotecnia
Imagine you are 'pushing' (推) a calculator (計) into the future to see what the numbers will be. Push + Calculate = Estimation.
Asociación visual
A graph where the solid line (known data) suddenly turns into a dotted line (the 推計) that points upward.
Word Web
Desafío
Try to find one news article today that uses the word '推計' and explain why they used it instead of '予測'.
Origen de la palabra
Composed of the kanji 推 (to push/infer) and 計 (to measure/calculate). It entered the Japanese lexicon during the modernization of the Meiji era to translate Western statistical concepts.
Significado original: To calculate by moving logically from known facts toward an unknown total.
Sino-Japanese (Kango).Contexto cultural
Be careful when using 'suikei' regarding sensitive topics like crime or poverty; ensure the data source is reputable to avoid sounding like you are making up numbers.
In English, we often use 'estimate' for everything from a car repair to a census. In Japanese, 'suikei' is much more specific to the census/statistical side.

Preguntas frecuentes
10 preguntasIt's better to use 'mitsumori' or 'keisan.' 'Suikei' sounds like you are a government official analyzing national financial trends. For a personal budget, it's too formal and implies complex statistical modeling you probably aren't doing.
'Suikei' (推計) focuses on the calculation (計) of numbers. 'Suitei' (推定) focuses on the determination (定) of a fact or state. Use 'suikei' for populations and 'suitei' for scientific assumptions or legal statuses.
Rarely. You might use it if you are discussing a serious news topic with friends, but in everyday life, 'yosou' (guess/prediction) is much more common.
You use 'kadai suikei' (過大推計). Similarly, 'underestimate' is 'kashou suikei' (過小推計).
It means 'estimated value.' It is the specific number that resulted from the 'suikei' process.
Yes, it is a suru-verb. You can say 'suikei suru' (to estimate).
Not necessarily. It can be used to estimate current numbers that are hard to count, such as the current number of endangered animals or the number of people at a large protest.
In terms of language, yes. 'Suikei' implies a scientific or statistical basis, whereas 'yosou' can just be a gut feeling.
It means 'population estimation' or 'population projection.' It is one of the most common pairings for this word in Japan.
No, weather uses 'yohou' (forecast) or 'yosoku' (prediction). 'Suikei' is not used for meteorological events.

Summary
推計 is the 'professional' way to say estimation. Use it when you are talking about numbers derived from data (like 'population estimates' or 'market projections') rather than personal guesses. Example: 将来の人口を推計する (To estimate the future population).
- 推計 (suikei) means 'estimation' based on statistical data and logical inference.
- It is a formal word used in business, economics, and government reports.
- Commonly used for population projections or market size calculations.
- It focuses on the mathematical process of finding unknown values from known ones.
Use for Big Data
Whenever you are dealing with millions of people or trillions of yen, 'suikei' is the most appropriate word to use in a professional setting.
The Passive Voice
In news and reports, 'suikei sareru' (is estimated) is much more common than 'suikei suru' (to estimate). It makes the statement sound more objective.
Suikei vs Suitei
Remember: Suikei = Numbers/Math. Suitei = Facts/Assumptions. If you are calculating a total, go with Suikei.
Impress Your Boss
Using 'suikei' in a presentation shows that you have a data-driven mindset. It sounds much more professional than saying 'I think the market is big.'
