HistorySaid Global Economic Dataset

Unified economic data from World Bank, IMF, and BIS. 215 countries. 99 indicators. 691,215 observations. One schema.

Overview

This dataset combines economic, social, and governance indicators from the World Bank (WDI and WGI), IMF World Economic Outlook, and BIS into a single normalized format. It is designed for researchers, data scientists, and developers who need cross-country time-series data without manual harmonization.

Coverage

Source	Indicators	Countries	Year Range	Update Frequency
BIS	1	106	1964–2026	Annual
IMF (WEO)	3	193	1980–2024	Annual
World Bank (WDI)	89	215	1960–2025	Annual
World Bank (WGI)	6	203	1996–2023	Annual
Total (unified)	99	215	1960–2026	—

Quick Start

Python

import pandas as pd
import matplotlib.pyplot as plt

df = pd.read_parquet("data/unified/all_indicators.parquet")

# GDP for the United States
usa_gdp = df[(df["country_code"] == "USA") & (df["indicator_id"] == "wb.NY.GDP.MKTP.CD")]
usa_gdp = usa_gdp.sort_values("year")

print(usa_gdp[["year", "value"]].tail(10))

plt.figure(figsize=(10, 5))
plt.plot(usa_gdp["year"], usa_gdp["value"] / 1e12)
plt.title("USA GDP (trillions USD)")
plt.xlabel("Year")
plt.ylabel("Trillions USD")
plt.grid(True)
plt.tight_layout()
plt.savefig("usa_gdp.png")
plt.show()

R

library(readr)
library(dplyr)
library(ggplot2)

df <- read_csv("data/unified/all_indicators.csv")

usa_gdp <- df %>%
  filter(country_code == "USA", indicator_id == "wb.NY.GDP.MKTP.CD") %>%
  arrange(year)

print(tail(usa_gdp %>% select(year, value), 10))

ggplot(usa_gdp, aes(x = year, y = value / 1e12)) +
  geom_line() +
  labs(title = "USA GDP (trillions USD)", x = "Year", y = "Trillions USD") +
  theme_minimal()

ggsave("usa_gdp.png")

year	integer	Observation year
value	float	Observation value (null if not available)
unit	string	Unit of measurement

Methodology

All country codes are normalized to ISO 3166-1 alpha-3. Indicator codes are namespaced by source (e.g., wb., imf., bis.) to prevent collisions. No interpolation, imputation, or gap-filling was applied. Missing values are null. Full methodology: METHODOLOGY.md

Validation

Schema compliance: 100% across all sources. Zero duplicate (country_code, indicator_id, year) tuples. Spot-check against source database: 100% match rate. Full report: VALIDATION.md

Updates

This is version 1.0. Update schedule to be determined.
