|According to a Pew Hispanic Center report, poverty among children in the U.S. is now highest in the Latino population.|
According to a recent report from the Pew Hispanic Center, poverty among Latino children is at an all time high and, for the first time, has displaced White children as the single largest group of children in poverty:
“More Latino children are living in poverty—6.1 million in 2010—than children of any other racial or ethnic group. This marks the first time in U.S. history that the single largest group of poor children is not white. In 2010, 37.3% of poor children were Latino, 30.5% were white and 26.6% were black.”
Also according to the report, while about two-thirds of the children’s parents immigrated to the United States, an overwhelming majority (86%) of the children were born in America. It seems that this increase, both relative and absolute, is another impact of the Great Recession:
“Prior to the Great Recession, more white children lived in poverty than Hispanic children. However, since 2007, that pattern has reversed. Between 2007 and 2010, an additional 1.6 million Hispanic children lived in poverty, an increase of 36.3%. By contrast, even though the number of white and black children living in poverty also grew, their numbers grew more slowly—up 17.6% and 11.7% respectively.”
The Census Bureau has released a microdata file that permits users to create tables updating the National Academy of Sciences’ experimental poverty estimates. This file will permit users to construct 2010 estimates. These estimates are different from the supplemental poverty measure, which is the topic for a Nov. 4 technical webinar. On Nov. 7, at a Brookings Institution seminar, the Census Bureau will release a supplemental poverty measure that complements, but does not replace, the official measure. This measure is the product of years of research and collaboration with other organizations, such as the National Academy of Sciences and the Bureau of Labor Statistics. A Census Bureau subject-matter expert will discuss supplemental poverty measure results and methodology at the seminar.
The microdata released on October 27, 2011 are available at: http://www.census.gov/hhes/povmeas/data/public-use.html.
The Cornell University Program on Applied Demographics (PAD) website possesses some great Census related resources. The first is a margin of error calculator for American Community Survey data which was created based on this U.S. Census Bureau document. The calculator allows you to enter values and operations in order to compute new margins of errors or test for significance of the difference between values.
Second, if you are looking for maps of current demographic data for the state of New York, then this site’s Census 2010 Atlas will be especially helpful. It has an easy to use index that allows users to choose what map to display. Once the map is displayed you can easily download a professionally prepared map in the form of a JPEG file.

|Cravify features an interactive map of tweets related to the Occupy Wall Street demonstrations.|
Cravify, a location based classified ads search engine, has developed a map of tweets related to the Occupy Wall Street movement. Similar to the map developed by ESRI, this map aggregates tweets related to the demonstrations and displays them over an easy to navigate basemap which, in the case Cravify, is Google Maps. Follow this link for more on Cravify or follow the developers on Twitter (@Trung_cravify and @humphrey_f).
|The ESRI Occupy Wall Street map now displays locations of demonstrations.|
A little over a week ago, I posted the ESRI produced Occupy Wall Street map. One of the items I noted was how the content was mostly limited to the occupation in Manhattan. Just over ten days later, the capabilities of this map have been expanded and the amount of content has grown exponentially. In addition to YouTube videos, Tweets, and images from Flickr, the OWS map now displays Occupy locations (which span the entire globe – see screenshot above) and a tool that allows users to quickly zoom to different cities located under the Areas of Interests button.
