The image displays a line graph depicting average cinema attendance percentages among various age groups in the US from 2000 to 2011. Four age groups are represented: "15-24," "7-14," "25-35," and "35 and over." Key data points include: In 2000, ages 15-24 began just below 50%, ages 7-14 around 35%, ages 25-35 near 30%, and ages 35 and over at approximately 15%. In 2002, 15-24 peaks just above 50%, while the other groups remain relatively stable with minor fluctuations. By 2004, all groups notably increase, with 15-24 around 60%, 7-14 increasing above 50%, 25-35 near 40%, and 35 and over slightly over 20%. In 2006, a decline is observed in all categories except 35 and over, which sustains. In 2008, further declines continue with 15-24 falling slightly below 50% and the other categories showing a gradual decrease. In 2010, 15-24 slightly recovers but does not exceed 50%, while other groups stabilize or decline modestly. By 2011, all categories experience a minor drop or leveling off, indicating either declining or steady attendance rates without significant recovery.
