In 2017, two smartphone-based travel surveys were conducted in two cities in Afghanistan. The surveys were conducted simultaneously in the capital city of Kabul and the non-capital city of Khost. This study investigated the reasons for non-response to the smartphone-based travel survey in association with individual attributes. Additionally, the reason for non-response to the Kabul and Khost surveys were compared. The comparison results revealed that the small reward for participation was the main reason for the non-response of males, while the reason for the non-response of females was mainly related to their privacy concerns, as well as their dependency with regard to decision making. The results also indicated that the non-response rate in the city of Khost was higher than that in the capital city of Kabul.
