Cleaned and English-Translated Long-Term Dataset of Japanese Household Disposable Income and Saving Ratio (1994-2026)

Description

- **Data Source:** Cabinet Office, Government of Japan (Reference series of the Quarterly Estimates of Household Disposable Income and Household Saving Ratio). - **Temporal Coverage:** 1994-Q1 to 2026-Q1 (Quarterly). - **Included Files:** 1. `japanese_household_macro_indicators_original.csv` (Original / Raw unadjusted time-series) 2. `japanese_household_macro_indicators_seasonally_adjusted.csv` (Seasonally adjusted time-series for trend analysis) - **Data Format:** Long Format (Tidy Data structure optimized for statistical analysis in R, Python, and Stata). - **Language:** Fully translated into English. - **License:** Creative Commons Attribution 4.0 International (CC BY 4.0). 1. **Machine-Readable Structure:** The original Japanese official tables use a nested, wide layout intended for human viewing. This dataset converts it into a continuous long format (`quarterly_id`, `economic_indicator`, `value`), making it ready for time-series and panel data analysis. 2. **International Standardization:** Japanese-specific temporal notations (e.g., "1994/1-3.") have been completely standardized into international ISO quarter formats (e.g., "1994-Q1"). 3. **Implicit Data Integration:** This dataset implicitly ensures synchronous chronological alignment of 14 key macro-economic indicators, including compensation of employees, net saving, and real disposable income, without any structural breaks. 4. **Comprehensive Analytical Options:** By providing both the original raw unadjusted series and the official seasonally adjusted series in a standardized Tidy structure, this dataset accommodates various econometric requirements. Researchers can seamlessly choose the raw series for consumption theory testing with seasonal dummies, or the seasonally adjusted series for clean, non-seasonal macroeconomic trend tracking.
