Data science professional development opportunities year in review

Posted on by

In 2021, there have been a healthy amount of professional development offerings for Indiana residents interested in developing their data skills. With many of us working remotely for part of the year, these offerings can be explored from work or home.

Earlier this year, Indiana’s Management Performance Hub hosted Indiana’s Data Day virtually over two days in March. You can watch the event here on the MPH website.

The MPH also offers a free ongoing proficiency program in data skills. You can take the classes online and earn points here.

In April, the Indiana SDC Program, IGIC and GENI co-sponsored a webinar with Lorraine Wright, “GIS in the 1700s! Indiana’s Historic Land Record Field Notes Digitized into Online Maps.” The recording is available here on YouTube.

The Census Bureau made several opportunities available upon the release of the 2020 Census PL-171 redistricting data in August. These data provided the basic final counts for the 2020 Census down to the census block level. Take a look at the Census Academy here, with the most recent video at the top of the page, The Comprehensive Course for Accessing 2020 Census Redistricting Data. View additional recorded webinars going back to 2016 here.

In October, also co-sponsored by IGIC and GENI, the SDC offered a webinar for accessing the data, “Accessing Data for Local Redistricting.”

In November, for Indiana Library Federation attendees, the SDC Program provided “Finding and Using Indiana’s Data Access Points, Census and More.” Thank you for those of you who were able to attend under challenging circumstances!

This month, the Indiana State Data Center hosted its annual training meeting online. Our three speakers from the Census Bureau were Andrew W Hait, Ronald Williams and Michael B Hawes. Recordings of these sessions will be available soon and each session will be eligible for one LEU for Indiana library staff.

In the summer of 2022, the Census Bureau will release a file called the DHC, or the Demographic and Housing Characteristics file. This will contain what has been called in the past – Summary File One, or SF1 data – for the 2020 Census. The State Data Center will provide access to the data and training for retrieving the data upon release.

Evaluating online resources for COVID-19 data

Posted on by

Resources online for COVID-19 data are already plentiful. You can do a search today and find data on the internet from all over the world, from many sources and for a variety of audiences. So, this is a good time to review the ways we evaluate sources for data and information.

There is no one perfect method for validating a data source. The usefulness of the data does not necessarily determine its reliability, nor does its timeliness or currency. When you choose a good book to read, you generally look for a good author, right? When you’re looking for good data, you need to choose a data source that has been verified by other sources.

This will ensure that the next time you search for data, you know where it’s from, what makes it a credible source, and how reliable it is.

If you do a Google search on “evaluating sources,” you can find several helpful mnemonics and acronyms that can help you remember how to search safely:

SIFT = Stop. Investigate. Find. Trace.

CRAP Test/CARP/CRAPPO/TRAAP = Currency. Relevance. Authority. Accuracy. Purpose.

CRITIC = Claim? Role of claimant? Information backing the claim? Testing? Independent verification? Conclusion?

PROVEN = Purpose. Relevance. Objectivity. Verifiability. Expertise. Newness.

Any one of these methods is useful for evaluating information sources. When it comes to data specifically, these are important questions to ask:

Where is the data from?
What was the source for this number or set of numbers? Did this come from a database that was available to you online? What organization created or collected the data? For what purpose? Was it a government information resource, a well-known national nonprofit organization or a college or university-owned research center? Was the data private or public information?

Who owns or maintains the data?
What is the name of the individual researcher or organization which conducted the survey or held the focus groups or interviews? What agency or organization published its findings with a publicized database or report? Who maintains the website you downloaded the data from?

When was the data made available compared to when it was collected?
What was the time frame for data collection? When was the database or report based on this data published? What date was the data released? When did you access the data?

How reliable is the data?
For how many years has the study been done? Can the data be verified? Can the study be reproduced? What methods were used to collect the data? Is the study peer reviewed? How are the data collection methods evaluated? How reputable are the organizations producing the data? Who else repeatedly uses this data?

Here are some examples of current, reliable sources for COVID-19 data:
The most recent COVID-19 data available for our state comes directly from the Indiana Department of Health. This is a government information source. The ISDH has been transparent in releasing current information daily throughout the pandemic. Since we get the numbers directly from the ISDH, it is our primary data source. We’re not relying on a secondary source for information.

For federal statistics on COVID-19, the Centers for Disease Control and Prevention provides a COVID Data Tracker with cases and deaths by state and county.

For global statistics on COVID-19, the Johns Hopkins Center for Systems Science and Engineering maintains a COVID-19 dashboard that shows cases by country and world region. It includes information about data sources and technical production of the database.

Libraries and the 2020 census

Posted on by

In December of last year, Kathy Kozenski from the Geography Educators’ Network of Indiana and I brought a giant 15′ x 21′ Indiana floor map1 to the Vigo County Public Library for a program called “Get On The Map!” Library patrons, ages 3 to 15, joined us in learning about state geography as we walked in socked feet across cities, lakes, rivers and forests.

We discussed the cardinal directions and talked with the students about where they had lived and traveled, and where they would like to go in the future. Despite their young ages, many had already been outside of the state and even outside of the country. We asked students to identify and locate map features. Lake Michigan, one of the map’s prominent features, was a favorite.

We asked what we might find in Indiana cities or towns. Answers were:

“Buildings!”
“Roads!”
“Trees!”
“Pets!”
“Cars!”

Part of my reason for this question was to introduce the idea of the census, so we asked what else a city or town needed in order to have all of these things.

“People!,” they answered.

This provided us with a chance to discuss how many people live in different areas, and that when there are more people we need more resources. We talked about the upcoming 2020 census, why we count people and why it is important to get an accurate count so that resources can be distributed where they are needed.

We followed our map exploration with the storied adventures of Fred the Fish. Made of a small piece of muslin, Fred swam in a river – a plastic container of water – next to several different sources of pollution. We poured in small amounts of dirt, oil and trash. We demonstrated the effects of these things on Fred, and talked about how important it is to notice the effects of human population on the surrounding environment.

With the 2020 Census approaching, librarians are on the forefront of community outreach, as our jobs will involve helping patrons report data to the federal government. This will be the first U.S. census in history to provide the opportunity for online response, and we expect to welcome our patrons to answer the census at our public computers.

In October of 2018, the American Library Association issued a policy brief entitled Libraries and the 2020 Census Vital Partners for a Complete Count that explains how libraries act as “trusted partners in achieving a complete count in the 2020 census” by:

  • Delivering information about the census and hosting community outreach activities
  • Providing internet access to enable respondents to complete the census form online
  • Serving as trusted messengers, including in hard-to-count communities
  • Training data users and providing access to census statistics for businesses and community members.

ALA recently hosted a free webinar, “Libraries and the 2020 Census” through its Chapter Advocacy Exchange. You can view the webinar here. The ALA president, assistant director of government relations and deputy director of public policy addressed the important role libraries play in ensuring a complete and accurate count of people. It featured librarians planning 2020 census outreach in Montana, California and Illinois.

In Indiana, there are several ways we can participate in planning for the 2020 census, which will take place a year from now, in March and April of 2020. Local communities are building Complete Count Committees, also known as CCCs, to encourage participation. At your library, you can help by hosting outreach efforts from the Census Bureau, promoting census jobs as they are available and incorporating census information in newsletters, social media and websites. Last week, the Census Bureau released its 2020 promotional guidelines. You can retrieve the PDF here.
