  <h4>Welcome to the Hurricane Cost Normalization Web App!</h4>
  
  <p>Our platform provides access to normalized hurricane damage data spanning from 1900 to 2024, allowing researchers, policymakers, insurance professional, and the public to better understand how hurricane costs have changed over time.</p>
  
  <h6>Our Data</h6>
  
  <p>The core datasets used in this app are based on research by Muller et al. (2025) published in <i>Bulletin of the American Meteorlogical Society</i>. This study updates and refines hurricane damage normalization methodologies to provide a more accurate picture of how historical hurricanes would impact today\'s society.</p>
  
  <ul>
    <li><b>PL22:</b> The Pielke-Landsea (2022) normalization that adjusts for inflation, wealth per capita, and population changes. This data has been updated to 2022.</li>
    
    <li><b>CL22:</b> The Collins-Lowe (2022) normalization that adjusts for inflation, wealth per housing unit, and housing unit changes. This data has been updated to 2022.</li>
    
    <li><b>MMP24:</b> The Muller-Mooney Population (2024) normalization with RMW weighting on affected population.</li>
    
    <li><b>MMH24:</b> The Muller-Mooney Housing (2024) normalization with RMW weighting on affected housing units.</li>
  </ul>
  
  <h6>Methodology Innovations</h6>
  
  <p>Our platform incoroprates several methodological innovations over previously used cost normalization formulas:
  
  <ul>
    <li><b>Radius of Maximum Wind (RMW) Data:</b> Using landfalling RMWs to identify impacted coastal counties.</li>
    
    <li><b>RMW Affected Area Weighting:</b> Determining affected population and housing unit figures based on RMW.</li>
    
    <li><b>Expanded Storm Coverage:</b> Inlcuding over 200 storms analyzed with interactive data.</li>
    
    <li><b>Up-to-date Data:</b> Using the latest population, housing unit, and economic data through 2024.</li>
