"Your starter report certainly saved me a considerable amount of time. I am just too busy to garner this needed data any other way. It truly would have taken hours of an employee's time or my own to get this much information. I was fortunate to find a company that had all the demographics that I needed and at a very reasonable price."

"My supervisor had assigned me the task of getting population data for the county for our required county education strategic plan. I had some information from Kids Count but need race, gender, age, etc. and the government census site was shutdown. I was so surprised to get a report within seconds and it had lots of charts and graphs that my supervisor liked."
