Final answer:
The declining labor force participation rate implies that the percentage of the population that is willing and able to work is declining.
Step-by-step explanation:
The declining labor force participation rate indicates that the percentage of the population that is willing and able to work is declining. This means that fewer people in the population are actively seeking employment or available for work. It does not necessarily imply that the unemployed rate is rising, as unemployed individuals may be leaving the labor force entirely.
