🗺️ Atlas Educação

Atlas Educação is a tool designed to visualize access to high-quality public high schools across Brazil. Leveraging datasets from the Brazilian Demographic Census (2010) and the School Census (2020), the platform highlights disparities in educational access and correlates them with demographic factors such as income, race, and gender.

📊 Core Metrics

1. Access Metric ($A_i$)

Formula: $A_i$ = $∑_{j∈[Dist(i,j)<16km]} R_j W_{ij} G_{ij}$

This metric combines demand and supply factors for high schools within a census tract, incorporating:

• $R_j$: Demand-Adjusted Supply: Calculated by dividing school capacity by the number of students aged 15-17 in the area;
• $W_{ij}$: Distance Weighting: Adjusts for proximity between students and schools;
• $G_{ij}$: Competition Weighting: Accounts for competition from neighboring schools within a 16 km radius.

It then sums up all access levels from each census tract to all other schools within 16 km to get the overall access for a census tract.

2. Quality-Access Metric ($H_i$).

Formula: $H_i$ = $A_i Q_i$

An extension of the Access Metric, incorporating School Quality ($Q_i$), weighted using the IDEB (Primary Education Development Index) scores of each school.

🗺️ Visualization

The map visualizes these metrics by representing each dot as a cluster of approximately 10 school-age children, allowing users to observe:

• Areas with higher or lower access to high-quality public schools;
• Correlations between access levels and socioeconomic factors.

💻 User Interface

1. Interactive Legend: Adaptable by layer, showing distributions for different demographic groups (e.g., racial distribution).
   
2. Layer Options: Access-Quality, Quality, Access, Income, Gender and Race.
   
3. Pop-up Information: Detailed data for each location, including:

• Census tract ID;
• Number of school-age children;
• Average monthly income;
• Access and quality percentiles.

🎯 Purpose and Impact

Atlas Educação aims to inform the public and policymakers about geographic disparities in educational access. By identifying underserved regions, it guides resource allocation to improve educational equity. With over 20,500 school data points and demographic data across 310,000 census tracts, this tool is a robust resource for addressing educational inequality in Brazil, where the majority of high school students rely on public education.
