This calculator helps estimate the crime rate for a given area. Crime rate is typically expressed as the number of crimes per 100,000 people. This calculation uses reported incidents and population data to provide an annualized rate.
function calculateCrimeRate() {
var reportedIncidentsInput = document.getElementById("reportedIncidents");
var populationInput = document.getElementById("population");
var resultDiv = document.getElementById("result");
var reportedIncidents = parseFloat(reportedIncidentsInput.value);
var population = parseFloat(populationInput.value);
if (isNaN(reportedIncidents) || isNaN(population) || population <= 0) {
resultDiv.innerHTML = "Please enter valid numbers for reported incidents and population. Population must be greater than zero.";
return;
}
// Crime Rate Formula: (Number of Reported Incidents / Population) * 100,000
var crimeRate = (reportedIncidents / population) * 100000;
resultDiv.innerHTML = "Estimated Crime Rate: " + crimeRate.toFixed(2) + " per 100,000 people.";
}
