You are using parseFloat to convert a string to a number. This is generally fine, but keep in mind that parseFloat will convert a string to a floating point number, which may not be what you want if you are dealing with population numbers. Consider using parseInt instead if you want to deal with whole numbers.

You are using the reduce method to calculate the sum of an array of numbers, which is a good use of this method. However, it's important to note that this method will return NaN if the array is empty. You might want to add a check to ensure that the array is not empty before using reduce.

You are using the toLocaleString method to format numbers with commas. This is a good approach, but keep in mind that the output will depend on the user's locale. For example, in some locales, the comma is used as a decimal separator. If you want to ensure that the number is always formatted with commas as thousands separators, you could use a more specific locale, like 'en-US'.
