Reading Statistical and Data-Driven Texts

By the end of this lesson, you will be able to read and interpret Japanese texts that present statistics, percentages, trends, and data comparisons at the N2 level.

In academic and news Japanese, data is often presented using specific vocabulary and grammatical patterns. Understanding these patterns lets you quickly grasp the meaning of numbers, trends, and comparisons without getting lost in complex sentences.

1. Key Vocabulary for Statistics

2. Expressing Percentages and Proportions

Pattern A: はを占める (~ wa ~ o shimeru) – "accounts for ~"占

• 若者の30%は大学生を占める。
  Wakamono no 30% wa daigakusei o shimeru.
  "30% of young people are university students."若者大学生占

Pattern B: に対して ( ni taishite) – "compared to / per ~"対

• 男性に対して女性の割合が高い。
  Dansei ni taishite josei no wariai ga takai.
  "The proportion of women is high compared to men."男性対女割合

3. Describing Trends

Pattern C: 傾向にある ( keikō ni aru) – "tends to ~"傾向

• 売り上げは減少傾向にある。
  Uriage wa genshō keikō ni aru.
  "Sales are on a decreasing trend."売上減少傾向

Pattern D: にわたって ( ni watatte) – "over a period of ~"

• 10年にわたって人口が増加した。
  10-nen ni watatte jinkō ga zōka shita.
  "The population increased over a 10-year period."年人口増加

4. Comparing Data

Pattern E: に比べて ( ni kurabete) – "compared to ~"比

• 去年に比べて今年の収入が20%増えた。
  Kyonen ni kurabete kotoshi no shūnyū ga 20% fueta.
  "Income this year increased 20% compared to last year."去年比今収入

Pattern F: ほどない (~ hodo ~ nai) – "not as ~ as ~"

• 今年の売上は去年ほど良くない。
  Kotoshi no uriage wa kyonen hodo yokunai.
  "This year's sales are not as good as last year's."今年売上去良

Example 1 (Proportion):
調査によると、女性の60%が週に一度運動すると答えた。
Chōsa ni yoru to, josei no 60% ga shū ni ichido undō suru to kotaeta.
"According to the survey, 60% of women answered that they exercise once a week."調査女性週一

Example 2 (Trend):
近年、スマートフォンの利用は増加傾向にある。
Kinnen, sumātofon no riyō wa zōka keikō ni aru.
"In recent years, smartphone usage has been on an increasing trend."近年利用増加

Example 3 (Comparison):
東京に比べて大阪の家賃は安い。
Tōkyō ni kurabete Ōsaka no yachin wa yasui.
"Compared to Tokyo, rent in Osaka is cheap."東京比大阪家

❌ Mixing up 割 (wari) and パーセント (pāsento)割

• 3割 = 30% (not 3%)割
• 5割 = 50%割
• 10割 = 100%割

Learners often think 3割 means 3%. Remember: 1割 = 10%.割

✅ Correct: 3割の学生がアルバイトをしている。
San-wari no gakusei ga arubaito o shite iru.
"30% of students work part-time."割学生

Fill in the blanks with the correct word from the box below.

| 割合 | 傾向 | 比べて | 占める |割合傾向比占

1. 若者の______がスマートフォンを持っている。
   Wakamono no ______ ga sumātofon o motte iru.
   "The ______ of young people own smartphones."若者持

   若者持

2. 去年に______今年の売上は上がった。
   Kyonen ni ______ kotoshi no uriage wa agatta.
   "Sales this year increased ______ to last year."去年今売上

   去年今売上

3. この地域の人口は減少______にある。
   Kono chiiki no jinkō wa genshō ______ ni aru.
   "The population of this region is on a decreasing ______."地域人口減少

   地域人口減少

Answers:

1. 割合 (wariai)割合
2. 比べて (kurabete)比
3. 傾向 (keikō)傾向

You now know how to:

• Read and understand proportions using 割合 and 占める割合占
• Describe trends with 傾向にある傾向
• Compare data using に比べて and ほど~ない比
• Correctly interpret 割 (wari) as 10% increments割

Next Step: Practice reading a short news article about population statistics or economic data. Try identifying all the data-related patterns you learned today. Then move on to the next lesson: "Interpreting Graphs and Charts in Japanese."
