Big Data Implications for the Production of Official Statistics

Dr. Daniel Pfeffermann at the Morris Hansen Lecture.

Dr. Daniel Pfeffermann, current President of the International Association of Survey Statisticians, discussed the implications big data might have for the production of official statistics at the recent Morris Hansen Lecture, an annual, open-to the-public education and outreach event held at USDA’s Jefferson Auditorium in Washington D.C. Pfeffermann stressed that big data may improve the timeliness of statistics while reducing response burden, but only if big data can be properly assessed, analyzed and interpreted to provide high quality, accurate information that is truly of value to users.

Unless you live completely off the grid, you likely have heard of, and contribute to, “big data,” the often-used catch phrase describing massive (and ever-increasing) volumes of information stored digitally on computers, servers and clouds.

From advertisers using data mined from customer interactions; to government agencies making data public so developers can create beneficial mobile apps; to farmers applying statistical data to determine their production and marketing practices, a wide-variety of people and industries use big data.

Maine Agriculture is “Up” in More Ways than One

Maine's agriculture and farm-related demographics are growing and diversifying each year. Check back next Thursday to learn more about the 2012 Census of Agriculture results as we highlight another state.

Maine's agriculture and farm-related demographics are growing and diversifying each year. Check back next Thursday to learn more about the 2012 Census of Agriculture results as we highlight another state.

The Census of Agriculture is the most complete account of U.S. farms and ranches and the people who operate them. Every Thursday USDA’s National Agricultural Statistics Service will highlight new Census data and the power of the information to shape the future of American agriculture.

When examining the status of Maine’s agriculture using statistics derived from the 2012 Census of Agriculture, the words “up” and “increase” appear quite often. Our state’s agriculture and farm-related demographics are growing and diversifying each year.

Both the number of farms and land in farms in Maine increased since the last Census of Agriculture in 2007. In fact, we have the most farms of the New England states, and the land in farms is up eight percent from 2007. In addition, the average size of a Maine farm is 178 acres, up seven percent since 2007. Organic production and aquaculture sales increased from between 2007 and 2012 as well: the value of aquaculture sales increased from $26.3 million to $75.1 million (ranking us eighth nationally) and organic products increased from $23.3 million to $36.4 million. Lastly, since the 2007 Census, the total market value of agricultural sales increased 24 percent, the average value of sales per farm increased 23 percent, and the value of crops, including nursery and greenhouse, went up 46 percent.

A Lifetime of Statistics

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.

As long as I can remember, I’ve had a passion for numbers and statistics. That’s why I’ve dedicated the last 39 years of my life to this amazing field.

I earned my degree in statistics in 1975 and shortly after that joined the U.S. Census Bureau, where I worked for 21 years.  At the Census Bureau, I had a really diverse experience, having worked on crime, housing, economics, and labor statistics, before ending up with the Census of Agriculture team. It was when this team transitioned to the National Agricultural Statistics Service (NASS) in 1997 that I joined my new home away from home at USDA. Read more »

The Census of Agriculture is the most complete account of U.S. farms and ranches and the people who operate them. Every week USDA’s National Agricultural Statistics Service will highlight new Census data and the power of the information to shape the future of American agriculture.

The final 2012 Census of Agriculture release is just around the corner. My passion for Census data is rooted not only in the benefits the Census results provide for agriculture as a whole, but also in the value it provides at the local level. To help you see and share all the ways Census data are working for you, USDA is kicking off a dialogue to share how the Census is working for you and your community.

Through Your Census. Your Story., you can become engaged in the Census Story. Read more »

How Does Ag Census Work?

Secretary Vilsack will present the preliminary results from the Census of Agriculture at the Agricultural Outlook Forum in Arlington, VA on Feb. 20.

Since 1840, the U.S. government has collected important census data on agriculture. The purpose of the Census of Agriculture is to account for all U.S. farms and to summarize the characteristics of those farms and their operators at the national, state, and county levels.

Today, the Census is the only comprehensive source of statistics on American agriculture that provides information by county. So, why do we call the numbers we produce estimates? Aren’t the numbers known exactly? These are the questions I am often asked when discussing the agricultural census.  The fact is that we do not know the numbers exactly so we produce the best estimates we can, given the data we collect.

Dive Deeper Into USDA Data with New APIs

Data consumers can now more easily leverage several of the most popular offerings from USDA’s Economic Research Service (ERS)!

To meet the needs of a growing community of data users, including application developers and researchers, ERS has just released seven new APIs (Application Programming Interface), enriched with shared services provided by other Federal agencies.  The APIs offer dynamic access to ERS’s atlases, traditional data sets, and indicators in machine-readable formats.  ERS has developed rigorous standards for data products; users will note the extensive metadata and full documentation and transparency provided for each of the data sets via APIs.

Experienced users may want to dive into the thorough documentation available on ERS’s Developer page; while those seeking a simpler path can leverage pre-built widgets and starter-code snippets available in jQuery, Python, and Ruby.  The geospatial APIs provide access to map layers via ESRI (or other mapping services, such as Mapbox and Google Maps).  The newly released APIs supplement the following data sets: Read more »
