GVU's Seventh WWW User Survey General Graphs

Age

Notes:

The average age of users responding to the Eighth survey is 35.7 years old. This average is slightly higher than the Seventh survey average (35.2), and continues the trend of increasing average age, which has been noted since the Fourth survey. The average age reported in this Survey is within the margin of error reported by FIND/SVP's 1997 American Internet User Survey of 36.5 yr. old. The consensus on average age between our data, collected through the Web, and FIND/SVP's data, collected through the traditional method of random telephone calls, helps increase our confidence that the core demographics in the Eighth Survey are representative.

Consistent with previous surveys, European respondents are generally younger than US respondents (30.19 yrs Europe vs. 36.53 yrs US), and the distribution of ages for European respondents is also more skewed toward the younger age ranges than the distribution for US respondents.

Also consistent with previous surveys, there appears to be no difference in average age or the distribution of ages between male and female respondents.

On average, novices who answered this survey were older than experts and intermediate users (Novice:38.6 yrs, Intermediate: 34.48 yrs, Expert: 33.49 yrs). The distribution of ages for novices was also flatter than the distribution for experts, which showed a peak around the ages of 21-30.
