Use the pаssаge belоw tо аnswer the questiоn. [1] A study in the iScience journal analyzed data on reading habits. The study entailed over 236,000 Americans who participated in the American Time Use Survey between 2003 and 2023. The findings perceived a cultural shift: fewer people are taking time in their day to read for enjoyment. This is a sustained, steady decline of about 3% per year. The researchers asserted that lower rates of reading for enjoyment every year may be a problem. [2] The decline wasn’t evenly spread across the population. Researchers found much lower frequency of reading for enjoyment among Black Americans than white Americans, people with lower income or educational attainment, and those in rural (country) areas — confirming strong differences in reading access and habits. [3] While people with higher education levels and women are still more likely to read, even among these groups, we’re seeing shifts. Among those who do read, the time spent reading has increased slightly, which may suggest a polarization, where some people are reading more in one area while many in the opposite area have stopped reading altogether.
