Economic indicators are numbers that describe how an economy is doing. The skill in SPM Economics is reading them carefully: what they measure, what base they are measured against and what a change does and does not tell you.
The topic sits within SPM Economics. Its ideas also connect to government and the economy, where indicators are the evidence.
What are the four reading skills?
Each one answers a different question about a set of figures, so the order below builds from simplest to most careful.
- Interpreting inflation data: what a rise in an index or rate says about prices.
- Distinguishing unemployment concepts: who counts in the labour force and who is unemployed.
- Reading growth indicators: what a change in output is measured against.
- Comparing nominal and real changes where required: separating a change in value from a change in quantity.
A second group of lessons, reading national economic indicators carefully, trains the habits that stop over-reading a number. Test everything with the indicators practice set.
Why does the base decide what a rate means?
Take a fictional town. Its labour force is 1 000, made up of 900 employed and 100 unemployed. The unemployment rate is 100 ÷ 1 000 = 10%.
A year later the employed number is 920 and the unemployed number is 80. The labour force is still 1 000, so the rate is 80 ÷ 1 000 = 8%.
A student who only sees “10% to 8%” can say the rate fell. A student who names the base adds that the labour force stayed at 1 000, so the fall comes from 20 workers moving from unemployed to employed. That extra sentence is what turns a description into an explanation.
Who should start where?
A student new to the topic starts with inflation data, since it introduces price levels and percentage change. A student comfortable with percentages can go straight to unemployment and growth, then finish with nominal and real.
If percentage change itself is the obstacle, practise it with the percentage base and index comparison explorer before reading the indicator lessons.
When does one-to-one help?
The lessons here give the method for free. A teacher sitting with you on a table of figures can hear the first thing you say about it and redirect you toward the base and the period. See online one-to-one Economics tuition if you want that.
