In the future, use of population-based surveys may be a faster and more accurate alternative than multiplier methods.
Internet-based surveys may be conducted by means of interactive interviews or by questionnaires designed for self-completion.
Thus, when Internet access is available, Internet-based surveys may be well received by respondents, particularly in household settings.

Replacing traditional case-reporting surveillance methods with less labor-intensive data collection methods, such as regular population-based surveys, may be suitable for following trends and estimating disease (10 ).

Empirical studies have shown that travel demand forecasting based on one-day travel behaviour surveys may be biased due to day-to-day variations in trip generation [1, 2].
Our mobile phone based survey apparatus may be particularly suited for conducting survey research in rural areas.
The survey was paper based and with the largest patient age demographic in the 25 35 age range and their corresponding comfort with smart phones, an electronic survey may be more appealing and have yielded a greater response rate.
Pensioners, not surveyed, may be more traditional.
