Final answer:
The statement about higher union density in Western Europe compared to the United States, apart from France, is true. Western European countries often have stronger labor union traditions and greater collective bargaining, leading to higher unionization rates.
Step-by-step explanation:
The statement that union density in Western Europe is significantly greater than in the United States, with the exception of France, is true. Union density refers to the proportion of workers who are union members. It is a measure of the strength and reach of labor unions within the workforce. In most Western European countries, the union density is indeed higher than in the United States. These countries typically have a stronger tradition of collective bargaining and workers' representation, which contributes to their higher unionization rates.
