Problem?Chosen:?B

 

Crime?is?a?problem?shared?by?essentially?all?major?metropolitan?areas.?It?is?often?a?priority?of?local?and city?governments?to?reduce the?spread of criminal activity?within?their?jurisdictions,?as?a?city’s?safety?is often?an?indicator?of?its economic?success?and?the happiness?of?its?citizens. As?such, it?is important to?be? able?to?gauge?a?city’s?safety?with?respect?to?crime?in?comparison?to?others,?in?order?to?determine?if?a?city? is?effectively?combatting?the crime?within?its?borders.?This?is?the?purpose?behind?our?mathematical?and? computational?model,?which?considers many?different?factors?contributing to?the?safety?of?a?city.

 

Our?model?generates?a?singular,?easily?interpretable?‘crime?rating’?that?can?be?compared?to?that?of?other? major?cities’?in?order?to?judge the?overall safety of?citizens.?To?do?this,?our?model?was?constructed? keeping?in?mind?that?we?would?need?to?be able?to?evaluate?My?City?as?accurately as?possible utilizing?the? massive?amount?of?information?provided?to?us.?At?the?same?time,?however,?we?would?also?need?to?be?able? to?compare?the?safety?of My City to?that?of?other?real-life?cities?which?may?not?have?as?readily?available? data.?As?such,?the?model?we?designed?is?not?only?accurate,?but?flexible.

 

We?constructed?our?model?around?the?following?parameters?that?would?contribute?to?a?city’s?safety:?the? number?of?crimes?taking?place over?a given period of?time,?the?number?of?people?affected?by?these?crimes,? the?severity?of?different?crimes,?the?efficiency of?police?in?arresting?criminals,?the proximity of?different? crimes?to?residential?areas,?and?the?relative?distribution?of?crime?throughout?the?city.?In?order?to?take?into? account?all?of?the crimes reported?and?listed?in?the?given?spreadsheet,?we?utilized?Microsoft?Excel?and? Java?programming?to?quickly?analyze the?data?and?yield?results in?a?timely manner.?We?were?also?able?to? use?far?less?comprehensive?statistics?from?online?sources?in?the?same?model?to?make?comparisons?between? My?City?and?real-life?cities?in?order?to?determine?safety.
