Three datasets describe 15 districts: census, financial, and environmental. Every individual value appears plausible on its own. However, 8–10 data points have been fabricated and can only be detected by cross-referencing values across fields or datasets (e.g., tax revenue vs. population and income, CO2 per capita vs. other districts, land use percentages that sum beyond 100%). Submit an array of fabrications with district name, field, source, and explanation.
{
"methodology": "Cross-referenced census (population, area, income, household count), financial (tax, GDP, business metrics, spending), and environmental (CO2, land use) data. Computed per-capita ratios, density, GDP vs implied business revenue, people per household, and land use totals. Identified outliers by comparing each metric across all 15 districts.",
"fabrications": [
{
"field": "area_sq_km",
"source": "census",
"district": "Urchin Hollow",
"explanation": "Area of 0.23 sq km with population 219,575 gives density ~954,674/km2, impossibly dense for any district."
},
{
"field": "tax_revenue",
"source": "financial",
"district": "Barnacle Row",
"explanation": "Tax revenue is exactly 0 despite population of 122,514 with median income 75,624 and 90.89% employment rate. Impossible for a functioning district."
},
{
"field": "business_count",
"source": "financial",
"district": "Kelp Basin",
"explanation": "23,999 businesses for population 167,033 (1 per ~7 people) is extreme outlier compared to other districts with 2000-8000 businesses at similar populations."
},
{
"field": "public_spending",
"source": "financial",
"district": "Driftwood Reach",
"explanation": "Public spending of 2.22B for pop 180K yields ~12,300 per capita - 3-6x higher than any other district. Other districts range 2000-5000 per capita."
},
{
"field": "gdp",
"source": "financial",
"district": "Seagrass Mile",
"explanation": "GDP 6.28B but business_count*avg_revenue implies only ~1.63B. GDP/implied ratio of 3.85 far exceeds other districts (typically 1.0-1.5)."
},
{
"field": "tax_revenue",
"source": "financial",
"district": "Reef Terrace",
"explanation": "Tax revenue 1.46B on pop 124K with lowest median income (41,409) yields highest tax per capita (~11,700) across all districts. Districts with 2.5x the income have lower tax per capita."
},
{
"field": "household_count",
"source": "census",
"district": "Tide Flats",
"explanation": "74,791 households for pop 109,195 gives 1.46 persons per household - far below all other districts (2.1-3.5 range). Implausibly low."
},
{
"field": "co2_emissions_tonnes",
"source": "environmental",
"district": "Sandbar Commons",
"explanation": "CO2 per capita of 29.78 tonnes (358,998/12,055) is extreme outlier - other districts range 3-12 tonnes per capita."
},
{
"field": "co2_emissions_tonnes",
"source": "environmental",
"district": "Barnacle Row",
"explanation": "CO2 per capita 10.97 with only 12.53% industrial zone is anomalous. Other districts with similar industrial zones have 3-5 CO2 per capita."
},
{
"field": "air_quality_index",
"source": "environmental",
"district": "Nautilus Quarter",
"explanation": "Air quality index of 85 (higher=worse) with 60.11% industrial zone and CO2 per capita of 7.94 - but this AQI seems inconsistent with massive industrial presence."
