Interactive Google Maps: Salary Gap between Men and Women in New Jersey

Rating:

Salary gap between male and female s narrowing in the United States but it seems that the situation in New Jersey is not that optimistic as most of the New Jersey women earn less than 80% then men, shown in U.S. Census data.

The report from the Pew Research Center found that women age 16 and above earned about $0.80 while men earned $1, or the hourly paid for women is $14.90 while hourly paid for men is $17.79. The salary gap among the ages from 25-34 is narrower.

Highlight from the report:

  • 21 municipalities in New Jersey where women earned less than half than men.
  • In some of the state’s wealthiest communities, e.g. Mantoloking, where women earned just 24% of the median man’s salary.
  • Women earned just about 1/3 of what men earned in Sea Girt, Saddle River and Teterboro.
  • Pay gap tends to be most narrow in urban areas close to New York City.

Map Review: 3.5/5 Stars

This map is an interesting tool that we can search locations to visit various amazing Christmas lights. However, since the map is a crowdsourced map, which information has to be approved and selected by administrator, and has been created for just a while, there is not enough information in the map. Alternatively, this map can collect more information in shorter time by enabling real “crowdsourcing” feature on the map that map users can directly add pins and information on the map, and the administrator can always edit the added pins in the control panel.

Heat Map: Suicide Rate in New Jersey

This week is National Suicide Prevention Week, and let’s take a quick reviews about the phenomenon in New Jersey, which is focusing prevention efforts on youth. Here we found an heat map and interactive charts for showing some statistic reports about suicides in New Jersey in past years

According to statistics from Centers for Disease Control’s CDC Wonder database, proportion of the population who died by suicide in New Jersey rose in 2010. Though New Jersey’s rate of 8.2 was the third-lowest among all states, and was only higher than New York and the District of Columbia, we cannot neglect the rapid rising suicides rate in NJ. Christopher Kosseff, a clinical psychology professor at Rutgers New Jersey Medical School, pointed out, “It has risen by more than 30 percent in the past 10 years.”

Here is a heat map for showing the suicides in New Jersey in 2006-2010, and you can mouse click the region for detailed statistics:

According to the report, the suicide rate for youth in 2011 was lower than the rate in 2010, and was also below the national rate.

You can find an interactive bar chart below and mouse hover the bars for details:
