Overview
This dashboard visualizes the population impact of bridges built and supported by Bridges to Prosperity (B2P) across Ethiopia. Each bridge plays a vital role in connecting rural communities to essential services such as healthcare, education, and markets.
Through spatial analysis and population data from WorldPop (2015–2024), this tool highlights how accessibility and connectivity evolve around these bridge sites over time.
📊 What You're Seeing
Bridge Points
Represent exact locations of B2P bridges built or supported across Ethiopia.
Buffer Zones
Show areas within 1 km, 3 km, and 5 km from each bridge. These zones help estimate how population distribution changes as proximity to a bridge increases.
Population Data (2015, 2023, 2024)
Derived from WorldPop's Population Count dataset to show how many people live within each buffer zone in different years.
Use the map controls to:
- Toggle between 1 km, 3 km, and 5 km buffers
- Switch years between 2015, 2023, and 2024
- Click on a bridge point to see detailed population summaries
📈 Why This Matters
Bridges are more than infrastructure — they're lifelines for rural connectivity. This visualization helps demonstrate the impact of bridge construction on community accessibility, supporting evidence-based decisions for future infrastructure investments and social development programs.
