Displaying information is probably the activity you will perform most frequently with IFs. The standard forecast (or "base case"), is loaded on your computer when you install IFs. IFs accesses the base case automatically when you start the model. You will create other cases/runs or more integrated scenarios as you learn to use the model in more depth (see Lesson 2).
The information of the base case and other runs or scenarios exists in the form of variables (concepts that vary over time) and you want to learn to display those variables. Let’s explore the many ways in which you can access information from a model run. Go to the Main Menu (below) and click on the Display option.
You will see multiple sub-options for display, several with sub-sub-options. Each of these sub-options provides different ways to display the results of IFs. These features can be broken down as either displaying variables focusing on geographic orientation or issue area. One important way to isolate forecast information on countries/regions is by using the Basic Country/Region sub-option. Additionally, if you would like to take a broad, global view of trends that are not country/region specific, use the Geographically-fixed Displays sub-option. The Specialized Display sub-option provides for a number of different issue area sub-sub-options for display. If you are looking specifically for demographic information, look for the Cohorts of Population and Cohorts of Education sub-sub-options. If you are looking for information reflecting the World Value Survey conducted out of the University of Michigan, you can find that under the Specialized Display sub-option. If you are more interested in issues of development and inequality, the Development Profile sub-sub-option, Millennium Development Goals sub-sub-option and the World Map, Lorenz Curve and Gini sub-sub-option allow for a variety of displays. Financial flows can also be tracked and forecast by using the Financial Profile, Social Accounting Matrix and World Bank Financial Flows sub-sub-options. Finally, if you are interested in and analysis that deals specifically with sustainability issues, click on the Advanced Sustainability Analysis sub-sub-option. The Self-Managed Display sub-option allow for the most flexibility in displaying variables. All of this information can be displayed in many formats, as either line or bar graphs, pie charts, world maps or as tables of data.
The following text provides a detailed analysis and overview of each display option described above. Read the descriptions, follow the links and try to answer the questions provided for each display option used in IFs. You will need to be using IFs when you work through these lessons. You may print off lessons in order to follow them closely while working or simply minimize the Help menu.
Here are some important categories of the Display Option choice on the Main Menu:
Flexible Displays: This display option allows more flexibility than the Geographically-fixed Displays. The Main Menu allows you to display different variables over time for specific countries. You are also able to display variables as the product of a specific Run-Result-File.
Geographically-fixed Displays: These are an especially quick path into looking at model results for selected variables and selected countries or country groupings. The user can choose results from different previously-run scenarios in the box at the bottom. Experiment!
Basic Report: This feature shows a basic subset of variables for any country or country grouping in the model. A double-click on a variable name brings up a table over time and across scenarios. The more advanced user can even customize the subset of variables displayed in the Basic Report (not possible on the Web).
Specialized Displays: These forms provide a great deal of focused information, most often on a single issue area of the model, such as population, education, values (using the dimensions from the World Value Survey), economic development, social accounting matrix flows and stocks, social development (the Millennium Development Goals), global distribution, or the environment (using the environmental sustainability system of the Finland Futures Research Centre). In some of these, such as the social accounting matrices, clicking on cells will drill deeper or provide information over time. Please explore and play with these extensive display screens.
Self-Managed Display: Although the most complicated display form to use, this is also the most flexible and complete. It allows the user to display any variable and parameter in the model in any display format. Computational options further allow combinations and transformations of variables.
This display provides geographically specific information that can then be displayed graphically or numerically over time. This option differs from Geographically-fixed Displays by offering the user more flexibility in choosing countries/regions or groupings.
After you have finished with the Flexible Displays topic, you should be able to do/answer the following:
- Graph more than one country at the same time.
- Choose a country that you are highly interested in. How is GDP at PPP forecast to change over time?
- Graph the Power index for China, USA and India. What trends emerge?
This display sub-option is useful for users of IFs who would like to quickly be able to display a selection of basic information graphically or numerically; those who want to forecast global trends for important variables using different Run-Result-File scenarios. These forecasts can then be viewed as a result of one of many run-result-files that can be found at the bottom of the screen.
After you have finished the Geographically-fixed Displays topic, you should be able to do/answer the following:
- Using the base case, is the percent of world population living on less than a dollar a day expected to increase or decrease? Graph this information to clearly see your results.
- Choose more than one Run-Result-File to compare to the base case. Graph World Population and see if there is any difference in the forecast.
- Do you know what parameters are changed in each of the Run-Result-Files? How would you find this out?
Basic Country/Region Report
This report provides geographically specific information that can then be displayed graphically or numerically over time. This option can display specific information for geographic units as small as Gabon to as large as the globe.
After you have finished with the Basic Country/Region Report topic, you should be able to do/answer the following:
- Change your display to Sub-Saharan Africa. Is the Knowledge Society Index forecast to increase or decrease over time?
- Switch to the Multiple-Grid format and choose the USA. Compare annual water usage for the year 2015 using different Run-Result-Files.
- Can you add a new variable? Feed demand is not a part of the default display, how would you go about adding it to your lists?
This display feature of IFs provides many different ways to present forecasts specific to countries or groups:
1. Specialized Display: Cohorts of Population: This display graphically presents demographic data as an age distribution, a traditional population pyramid, a fertility distribution or a mortality distribution.
After you have finished with the Cohorts of Population topic, you should be able to do/answer the following:
- Switch the Cohorts of Population display to Italy. In the year 2000, what would you say is the approximate ratio of females to males in the 80-84 cohort?
- Switch the Cohorts of Population display to the Fertility Distribution for Russia. As you advance over time, which cohorts of the population are having more children and which are having fewer?
- Switch the Cohorts of Population display to the Mortality Distribution for Africa & Mideast. Which sex is dying at a younger age, males or females?
2. Specialized Display: Cohorts of Education: The Education Cohorts display is a population pyramid distribution that separates 5 year age cohorts of the population divided by sex and visually distinguishes educational attainment.
After you have finished with the Cohorts of Education topic, you should be able to do/answer the following:
- Select Iran as a country you would like to learn more about. In the 20-24 year old cohort, which sex has more tertiary education? As you advance over time, what ends up happening?
- Change your display to show the entire world (this may take a moment as IFs has to calculate each country separately and then aggregate the information). Now, advance to the year 2100. (Hint! There is a faster way to advance than simply clicking on the Advance button).
- Display the Education Cohort for Germany. In what year does it appear that females of the 20-24 cohort approach full tertiary educational attainment?
3. Specialized Display: Cohorts of World Value Display: This feature of IFs graphically builds on an ongoing project initiated at the University of Michigan to track and understand global value trends.
After you have finished with the Cohorts of World Value Display topic, you should be able to do/answer the following:
- From the main World Value Survey menu, select Afghanistan and toggle between the three main displays: Materialism/Postmaterialism (MATPOSTR), Survival/Self-Expression (SURSE) or Traditionalism/Secular-Rationalism (TRADSRAT). Do you understand each of these displays?
- Choose Africa and SURVSE. Advance through time until the youngest age cohort moves from Survival into Self-expression. In what year is this forecast expected to take place?
- Using TRADSRAT, can you find a country that has some population cohorts that are predominantly traditional and some population cohorts that are predominantly secular/rationalist?
4. Specialized Display: Development Profile: This feature of IFs is designed to explore the contribution to development from Human Capital, Social Capital, Physical Capital and Knowledge for countries/regions or groups. This information can then be forecast over time and displayed graphically or in a table.
After you have finished with the Development Profile topic, you should be able to do/answer the following:
- Find one country where human capital contributes highly to annual growth and another country where low levels of human capital hinder annual growth.
- Create a line graph that shows government corruption for South East Asia over time.
- How substantially are France’s R&D expenditures expected to grow over time?
5. Specialized Display: World Map, Lorenz Curve, Gini: This option allows users to display global inequality for various variables as a map, a Lorenz curve or a Gini Coefficient.
After you have finished with the World Map, Lorenz Curve, Gini topic, you should be able to do/answer the following:
- Display Gross Domestic Product at Purchasing Power Paridy as a world map. Change the map to display the results as an equal count or an equal interval.
- Produce a Lorenz Curve for Energy Demand. How equal is the distribution?
- The above Lorenz Curve for Energy Demand also produced a Gini Coefficient. Was this Gini Coefficient showing a relatively equal distribution of demand or a relatively unequal distribution of demand?
6. Specialized Display: Financial Profile: Presents users of IFs with the option to view financial information for a given country or group and then track it over time numerically or graphically.
After you have finished with the Financial Profile lesson, you should be able to do/answer the following:
- Create a line graph that shows government debt for the United States over time.
- Display the total reserves of the world overtime as a percent of the reserves in the year 2000. Graph this display.
- Switch from country to country looking to see who has a higher government debt. Are there any countries with very high government debt that surprised you?
7. Specialized Display: Social Accounting Matrix (SAM): The Social Accounting Matrix (SAM) allows users to view domestic financial flows for a given country and display them overtime.
After you have finished with the Social Accounting Matrix topic, you should be able to do/answer the following:
- What is the total flow from American firms to the government in the year 2010?
- How does IFs forecast the flows from Chinese households to the Chinese government? Will increase or decrease in the future? Present this information graphically.
- View the total flows from all of the governments of Western Europe from governments to households as a percentage change from the year 2000. Display this information as a line graph.
8. Specialized Display: Millennium Development Goals: This displayMillennium_Development_Goals allows users of IFs to track overtime how well countries are achieving the eight Millennium Development Goals.
After you have finished with the Millennium Development topic, you should be able to do/answer the following:
- From the Main Menu, toggle between the different Millennium Development Goals for Bangladesh. Looking at the graph, is Bangladesh meeting these goals?
- Change your display from countries/regions to groups. Can you find a group that is making fast progress and a region that is not progressing at all?
- Using the countries/regions option on Millennium Development Goals, find one country/region that is making historical progress on the issue of Gender Equality and one country/region that is making a historical regression on the issue? In your exploration, did you find any interesting cases?
9. Specialized Display: World Bank Financial Flows: This option tracks monetary flows between countries and the World Bank, whether they are subscription or debt payments. For countries who receive World Bank financing, the bottom of the form will also show the general expected use of those funds within the country.
After you have finished with the World Bank Financial Flows topic, you should be able to do/answer the following:
- Pick one country that you believe may have received a lot of money from the World Bank. Graph these funds over time. Was the country you selected really receiving a lot of money?
- Produce a graph for any given country that displays results as a percentage change of the base year for loans taken from the World Bank.

11. Specialized Display: Evaluate Priorities: This display feature of IFs allows users to set priorities on variables that are of importance to their research. This tool is useful for analyzing different Run-Result-Files in order to more fully achieve explanatory or normative forecasts.
After you have finished with the Evaluate Priorities topic, you should be able to do/answer the following:
- How do I change priority for one variable I am highly interested in?
- What if my variable does not appear on the main screen of Evaluate Priorities? How can I place it there?
- What does the cumulative score measure at the bottom right of the Evaluate Priorities Main Menu?
The most flexible approach to displaying results from the model is the Self-Managed Display, also known as the Flexible Display. It can be reached from the Main Menu, the Display option, and the Self-Managed Display sub-option.
After you have finished with the Self Managed Display topic, you should be able to do/answer the following:
- Compare Total Fertility Rates with levels of educational attainment. What trends emerge?
- Produce a graph that shows GDP at PPP for a number of countries you are interest in. How do the different Run-Result-Files that you have stored on your version of IFs change the forecasts?
- Explore the variables used in IFs. Find one of specific interest to you and experiment with it.
