Employment is the total number of people
working for pay
Unemployment is the total number of people who
are actively looking for work
Labor force is the total employed and
unemployed
(Please note – people who do not work and are
not actively seeking employment are not part of
the labor force.)
The unemployment rate – the % of the labor force
who are unemployed is a good indicator of what
conditions are like in the job market

Output – the quantity of goods and services
produced
Aggregate output – the economy’s total
production of goods and services for a given
time period

Inflation – the rising overall price level, the
price of a can of soda when I was 10 was .25,
now I pay .75
Deflation – the falling overall price level, the
price of gas last summer was over 4.00,
yesterday I paid 2.35
Price Stability – when the aggregate price
level is changing only slowwwwwly.

all other factors remain unchanged and
economists can focus on one change at a
time
