Did white collar workers outnumber blue collar workers in the 1960s?

In the 1960s, blue-collar workers still outnumbered white-collar workers in the United States, reflecting the economy's reliance on manufacturing and manual labor. However, the trend began to shift as the service sector grew and more people entered office-based roles. By the end of the decade, the gap between the two categories was narrowing, setting the stage for future demographic changes in the workforce.
