Estimating the Size of a Small Population

Estimating the Size of a Small Population

Let me tell you a wonderful story, a statistical detective story of sorts.
During the summer, you may have seen statistics released from the 2010 Census Summary File 1 on same-sex couple unmarried partner households.
We noticed that reported counts of same-sex couples from the 2010 census were much higher than similar estimates from American Community Survey at earlier years. Our demographic analysts had some immediate ideas, explained nicely in this video:
So we suspected that the format of the nonresponse followup form was the culprit. If that were the case, one should see some obvious mismatches between the name of the person written on the form and the recorded sex of that person. Bingo! A qualitative inspection of some of the records showed suspicious combinations (e.g., “Harold” recorded as a “female”). Past research led us to believe that the name entered was likely to be more accurate than the recorded sex.

Citizen-centric statistics?

The factlab way publishing statistics in newspaper


This is how the Dagens Nyheter, the largest newspaper in Sweden, used factlab to show their readers public data and statistics that compare different things between Denmark and Sweden in connection with the Danish election last week. They give you only a few examples, and leave it to the readers to make further research if they want to compare anything else or if they want to compare with some other countries. With even more free statistics, factlab become even more attractive for all citizens.

You can easily get factlab in English or other languages, just click on "Change Settings".

If you want to compare with other countries, just click on "Show selection" and mark any country you want.

Public Data Explorer a Google Labs Survivor

From: Search Engine Land

google-g-logoSeveral Google Labs projects have learned their fate as the company continues to close down Google Labs as part of a larger streamlining effort.

However, Public Data Explorer survives – this tool launched in 2008 and lets users search and compare sets of public data, such as comparing unemployment rates across different states. This has now graduated out of Google Labs. Also, the related Dataset upload for Public Data Explorer tool is also graduating from Google Labs.

From ReadWriteWeb

mchui.jpg"Big data enables new ways to create value, it's going to change the basis of competition," Michael Chui of the McKinsey Global Institute said this morning to kick off O'Reilly's big data conference, the Strata Summit. The next two days are all about the rise of information that has to be dealt with on scale, big data, and its consequences. "It will change the way companies, sectors and economies compete," says Chui.
McKinsey published an exhaustive 150 page report on big data this Spring, which argued that data will soon become an economic input as important as labor and capital. It's not just about pure economics, though. As Edd Dumbill, chair of Strata, put it today, our relationship with big data needs to serve humans - not turn humans into the servants of machines and information overload. "We know that big data can help us, it may be the case that big data has to help us."
