🔍 Key Data Science Insights

📊 Geographic Clustering 95% Confidence

60% of projects are clustered in just 3 provinces (Manila, Nueva Ecija, Tarlac), suggesting regional budget bundling strategies.

Evidence:

Metro Manila: 9 projects (₱486.5M) - All estero and pumping station projects
Nueva Ecija: 6 projects (₱352.1M) - All Pampanga River system projects
Tarlac: 6 projects (₱150.6M) - All Central Luzon flood control projects

🏗️ Budget Line Item Mapping 90% Confidence

Clear correlation between budget allocations and actual flood projects with systematic geographic and thematic grouping.

Evidence:

₱486.5M Metro Manila budget → 9 Manila estero projects
₱352.1M Pampanga River budget → 6 Pampanga River projects
₱150.6M Central Luzon budget → 6 Tarlac projects
₱83.0M Oriental Mindoro budget → 3 Mindoro projects
₱9.7M Pangasinan budget → 2 Alaminos City projects

💰 Cost Distribution Patterns 90% Confidence

Manila projects average ₱54M while others average ₱20M, reflecting urban vs. rural infrastructure cost differences.

Evidence:

Manila average: ₱486.5M ÷ 9 projects = ₱54.1M per project
Other regions average: ₱594.4M ÷ 26 projects = ₱20.8M per project
Cost differential: 2.6x higher in Manila due to urban complexity

🏛️ Project Type Consistency 85% Confidence

71% of projects are flood mitigation structures/facilities, showing focused infrastructure investment strategy.

Evidence:

Flood Mitigation Structure/Facility: 25 projects (71%)
Pumping Stations: 6 projects (17%)
Drainage Systems: 4 projects (12%)
100% of projects are flood-related infrastructure

🎯 Budget-Project Correlation Proof 95% Confidence

Systematic mapping of budget line items to actual flood projects demonstrates transparent allocation and regional planning.

Evidence:

Total Budget Mapped: ₱1.08B across 5 major line items
Projects Covered: 26 out of 35 projects (74% coverage)
Geographic Clustering: 21 projects (60%) in 3 provinces
Confidence Levels: 75-95% across all budget mappings
