Exploring a range of educational outcomes within and across countries: Sub-national data supplement to Education at a Glance 2015

By Lauren Musu-Gillette and Tom Snyder

Situating educational and economic outcomes in the United States within a global context can help researchers, policy makers, and the public understand how individuals in the U.S. compare to their peers internationally. The annual publication Education at a Glance produced by the Organisation for Economic Co-operation and Development (OECD) provides information on the state of education in many countries across the world. While these data are instrumental in helping us to understand how the U.S. compares to other OECD and partner countries on a number of key educational and economic outcomes, national averages can mask the high degree of variation that can occur within individual countries. In order to address this, several OECD and partner countries, including the U.S., provided sub-national data on several select indicators previously only available at the country level.   

These data, posted on the NCES website, serve as a supplement to Education at a Glance 2015 and provide select sub-national data for six indicators in this edition. These include data on educational attainment by selected age groups, employment rates by educational attainment, annual expenditure per student, enrollment rates by age, enrollment rates in early childhood and primary education, and enrollment rates and work status of 15-29 year-olds.

In order to understand the amount of variability in an indicator for a particular country, we can compute a ratio of the state, territory, or region with the highest percentage to that with the lowest percentage on any given metric. For example, within the United States, the percentage of 25- to 34-year-olds who completed any level of postsecondary education in 2013 ranged among the states from 30 percent in Nevada to 55 percent in Massachusetts.

The ratio of high to low percentages of 25- to 34-year-olds completing postsecondary education in the United States (2.4) was among the largest of the reporting countries.  The ratio was higher in Brazil (5.8) with a range of 6 to 31 percent, and in Spain (2.8), with a range from 21 to 58 percent. The U.S. ratio was slightly higher than in Canada and Russia (both 2.3).  The ratio was lower in Sweden (1.8) and lowest in Slovenia (1.0), Ireland (1.2), and Belgium (1.2). The high to low ratio between OECD countries was 2.8, ranging from a low of 24 percent to a high of 68 percent.

NOTE: Countries are ranked in ascending order of the average percentage of the 25-34 year old population with postsecondary education. Data years differ. Data for Canada is from 2012, while data for the United States and Brazil is from 2013. Data for all other countries is from 2014.

Regional policy makers can benefit most from the comparisons presented in Education at a Glance when they can compare the results from their own sub-national areas with national and sub-national data from other countries. It is not surprising that large federal countries, such as Canada, Germany, and the United States, in which education is largely controlled by regional authorities, might have large internal variations. But, many other countries with centralized education systems such as Spain and Sweden have substantial variations within their countries as well. These new sub-national data can help illuminate these differences and provide additional information to U.S. states on how they compare to their peers both within the U.S. and internationally. 

Distance education: Learning in non-traditional settings

By Lauren Musu-Gillette

Distance education courses and programs provide students with flexible learning opportunities. Distance education has become increasingly common at the postsecondary level. Many postsecondary institutions offer at least some online courses, while other institutions exclusively offer online programs and courses taught exclusively online. NCES collects data on distance education through the Integrated Postsecondary Education Data System (IPEDS) and the National Postsecondary Student Aid Study (NPSAS).

IPEDS data on distance education provides information on the number and percentage of students participating in distance education at different types of institutions. In fall 2013, about 4.6 million undergraduate students participated in distance education, with 2.0 million students (11 percent of total undergraduate enrollment) exclusively taking distance education courses. Of the 2.0 million undergraduate students who exclusively took distance education courses, 1.1 million students (6 percent of total undergraduate enrollment) were enrolled in programs located in the same state in which they resided, and 0.8 million (4 percent of total undergraduate enrollment) were enrolled in a different state.

At the postbaccalaureate level, some 895,000 students (31 percent of total postbaccalaureate enrollment) participated in distance education in fall 2013, with 677,000 students (23 percent of total postbaccalaureate enrollment) exclusively taking distance education courses. Of the students who exclusively took distance education courses, 273,000 students (9 percent of total postbaccalaureate enrollment) were enrolled in programs located in the same state in which they resided, and 362,000 students (12 percent of total postbaccalaureate enrollment) were enrolled in a different state.

The percentage of undergraduate students participating exclusively in distance education programs differed by institutional control. In fall 2013, a higher percentage of students at private for-profit 4-year institutions exclusively took distance education courses (58 percent) than did students at any other control and level of institution. Similarly, at the postbaccalaureate level, the percentage of students who exclusively took distance education courses in fall 2013 was higher for those enrolled at private for-profit institutions (79 percent) than for those at private nonprofit (19 percent) and public institutions (16 percent).

Data on distance education in IPEDS is at the institution level, and therefore does not provide data on how distance education may differ by student characteristics. However, NPSAS contains both institution- and student-level data and can therefore be used to examine whether participation in distance education differs based on student’s demographic characteristics. For example, findings from NPSAS show that a higher percentage of older adults enrolled in distance education classes than younger adults. In 2011–12, a higher percentage of undergraduates 30 years old and over took distance education classes or their entire degree program through distance education (41 percent and 13 percent, respectively) than undergraduates 24 to 29 years of age (36 percent and 8 percent, respectively) or undergraduates 15 to 23 years of age (26 percent and 3 percent, respectively).

Findings from NPSAS also show that enrollment in distance education was higher in 2011-12 than in previous years in which these data were collected. A higher percentage of undergraduates took distance education classes in 2011–12 (32 percent) than in 2007–08 (21 percent) or in 2003–04 (16 percent). Also, a higher percentage of undergraduates took their entire degree program through distance education in 2011–12 (6 percent) than in 2007–08 (4 percent) or in 2003–04 (5 percent).

Enrollment in distance education will likely continue to grow as additional institutions offer individual courses, or even entire degree programs, online. Drawing on new technologies, the scope of distance education activities have expanded to reach millions of students. Current and future NCES data collections will continue to monitor this trend.

Reading for fun: Using NAEP data to explore student attitudes

By Lauren Musu-Gillette

The National Assessment for Education Progress (NAEP) is well-known as one of the key resources for information about the academic progress and performance of U.S. students. But did you know that NAEP also collects other important data on students’ behaviors and attitudes? For example, NAEP Long-Term Trend reading assessments have asked students how often they read for fun. Using these data, we can see how the frequency of reading for fun differs by student age and over time. These data can also be examined in conjunction with students’ reading assessment scores on NAEP.

A higher percentage of younger students reported that they read for fun almost every day than older students. In 2012, about 53 percent of 9-year-olds reported that they read for fun almost every day, compared to 27 percent of 13-year-olds and 19 percent of 17-year-olds. Conversely, about 27 percent of 17-year-olds said they never or hardly ever read for fun compared to 22 percent of 13-year-olds and 11 percent of 9-year-olds. For 17-year-olds, the percentage who reported that they read for fun almost every day decreased over time, from 31 percent in 1984 to 19 percent in 2012.

There were also differences in reading assessment scores by frequency of reading for fun. In 2012, students who were 17-years-old and read for fun almost every day had higher scores (302 points) than those that never or hardly ever read for fun (272 points). The same was true for 13-year-olds (276 vs. 249 points, respectively) and 9-year-olds (226 vs. 208 points, respectively). Note, however, that comparisons like these between reading assessment scores and frequency of reading for fun cannot be used to establish a cause-and-effect relationship. 

Other questions about students’ reading behaviors and attitudes are included on the main NAEP assessments. For example, in addition to a question about the frequency of reading for fun, the 2015 questionnaire included the following items:

  • About how many books are there in your home?
  • How often do you talk with your friends or family about something you have read?
  • Reading is one of my favorite activities (with response options: this is not like me, this is a little like me, and this is a lot like me)

Questions like these can be compared with students’ assessment scores to examine how attitudes, behaviors, and achievement may be related.

The growing field of statistics

By Lauren Musu-Gillette

In 2010, the United Nations General Assembly adopted October 20th as World Statistics Day. Over 130 countries and areas of the world joined in the inaugural World Statistics Day celebration. October 20, 2015 is the second time World Statistics Day will be celebrated. This day is intended to highlight the important contributions statistics and statisticians make to a wide array of national and international activities.  The theme for World Statistics Day 2015 – “Better data. Better lives.” – reflects the important role that statistics plays in helping businesses, governments, and the public make informed decisions.

Careers in statistics are varied, and cover a range of areas that include politics, economics, finance, and governance. As the interest in data-driven decision making grows, so too does the demand for statisticians.  The Bureau of Labor Statistics estimates that the job growth for statisticians will be much faster than the average overall job growth. As a reflection of that growth, the number of degrees conferred in the field of mathematics and statistics has increased over the last decade. For example, in 2002–03 there were 12,505 bachelor’s degrees conferred in mathematics and statistics and in 2012–13, there were 20,453 degrees conferred in this field. During this period, the number of degrees conferred also increased for master’s degrees (from 3,620 to 6,957), and doctor’s degrees (from 1,007 to 1,823).

While the number of degrees conferred in mathematics and statistics increased for both males and females over the past decade, the percentage of bachelor’s degrees conferred to males in 2012–13 was higher than the percentage for females (57 vs. 43 percent). Similarly, a higher percentage of master’s degrees in this field were conferred to males in 2012–13 (60 vs. 40 percent), and the same was true for doctor’s degrees (71 vs. 39 percent).

By collecting and disseminating data on the number of degrees conferred in different fields, NCES can help researchers, policy-makers, and the public to determine whether the changing demands of the workforce are likely to be met.

Did you know that NCES has a Kids' Zone?

By Lauren Musu-Gillette

Join us in celebrating World Statistics Day on October 20, 2015!

While most of NCES’ products are designed for education stakeholders such as teachers, school administrators, and researchers, the Kids' Zone is designed for use by some of our most important consumers - students! The Kids' Zone contains features such as a dice game that helps students learn about probability and statistics, links to online tools where students can find information on their school, and a graph creation tool.

According to the graph above, which element forms the second greatest portion of the earth’s crust?

  1. Oxygen
  2. Silicon
  3. Aluminum
  4. Iron
  5. Calcium

The above question is an example of an 8th grade mathematics question that can be answered using the Dare to Compare feature of the NCES Kids' Zone. This feature of the NCES Kids' Zone allows you to choose questions (5, 10, 15, or 20) from different subject areas (Civics, Economics, Geography, History, Mathematics, or Science) asked at different grade levels depending on the subject selected (4th grade, 8th grade, 9th grade, or 12th grade). After you answer the questions, your answers are scored and you can see how you compared to students in that age range either nationally or internationally. For example, on this question 87 percent of U.S. 8th graders selected the correct response of Silicon on a past NAEP assessment.

Create a Graph can be used by teachers and students. In fact, Create a Graph is one of the most frequently visited pages on the NCES website. Using this tool, you can create bar graphs, line graphs, pie graphs, area graphs, or you can choose an XY plot in order to plot individual points. For example, everyone in class could answer a series of questions using Dare to Compare. Then, the class could calculate what percentage of the class responded correctly to certain items and graph that percentage along with the percentage of students who answered the question correctly in different regions of the U.S., or different countries. We encourage you to join us in celebrating World Statistics Day on October 20, 2015 by planning a fun activity, such as the one suggest above, using the NCES Kids' Zone. Follow us on Twitter @EdNCES for other ideas and announcements about World Statistics Day.

There are a lot of fun features on the NCES Kids' Zone – so go ahead and explore!
