Input: Article: The Uniform Crime Reports (UCR) compile data from over 17,000 law enforcement agencies across the country. They provide detailed data regarding the volume of crimes to include arrest, clearance (or closing a case), and law enforcement officer information. The UCR focuses its data collection on violent crimes, hate crimes, and property crimes. Created in the 1920s, the UCR system has not proven to be as uniform as its name implies. The UCR data only reflect the most serious offense in the case of connected crimes and has a very restrictive definition of rape. Since about 93% of the data submitted to the FBI is in this format, the UCR stands out as the publication of choice as most states require law enforcement agencies to submit this data.

Now answer this question: Where was the UCR created?

Output: 1920s
