The Statistical Office of the Republic of Slovenia (SURS) marked World Walking Day on 1 October with a snapshot from its 2025 passenger daily mobility survey. Residents aged 15–84 made one in every five daily trips on foot. An average walking trip was 2.2 kilometres long and lasted 29 minutes. These are survey estimates about trips in a defined population and period, not a count of every walk in Slovenia, a measure of exercise, or an assessment of pedestrian infrastructure. The release makes the two useful dimensions visible together: walking’s frequency among recorded trips, and the average distance and duration of those trips.

The denominator is trips, not people. “One in five” means one fifth of the trips recorded in the survey were made by walking; it does not say that one fifth of residents walked, that each resident walked once per five days, or that walking accounted for one fifth of total distance. A person could report no trip on the observation day or several trips. SURS’s general 2025 mobility release says residents aged 15–84 made an average 2.3 trips per day, and 24% made no trip in the defined 100-metre to 300-kilometre range on an average day. It also reports an average 14.4 kilometres and 24 minutes per trip across modes. Those whole-mobility averages are a different measure from the 2.2 kilometres and 29 minutes for walking trips.

The survey describes residents of Slovenia aged 15–84 living in private households. SURS selected respondents from its Central Population Register and demographic database. In 2025, it used two independent samples: a stratified systematic web sample of 18,060 people and a stratified two-stage field sample of 11,200, for 29,260 selected people in total. Data were collected from 19 March to 16 June through web interviews and face-to-face interviews. The target was each respondent’s trips on one selected day. A survey observation day ran from 03:00 until 02:59 the next morning, so late-night and early-morning travel could be counted. Working and non-working days were distributed to represent both types of day.

SURS defines a trip as movement on a public road or path for a purpose such as work, education, shopping or leisure. Only trips longer than 100 metres and no longer than 300 kilometres were included. Trips made entirely abroad were excluded, although a trip could start or end across the border. Walking and running are listed modes. Distance includes movement on public roads and paths; movement on private land, such as a garden or field, is excluded. If a trip combines multiple modes, the main mode is the one used for the longest distance within that trip. This matters when reading a walking share: a journey with a short walk to transit and a longer bus leg is classified by the longer-distance mode, not necessarily as a walking trip.

The office weights the web and field samples separately to account for selection probabilities, non-response and calibration, then combines the final weights. It edits records and may impute missing answers. Estimates can have sampling, non-response and measurement error; SURS flags less reliable estimates and suppresses those with a coefficient of variation above 30%. The survey is collected every four years, and seasonal adjustment does not apply. Collection took place in spring 2025; SURS states the period included holidays and an active school year without weather extremes and considers it representative of the calendar year. In September, SURS revised annual trip totals for 2017, 2021 and 2025 after finding an underestimation in the annual calculation; it said shares by trip breakdown, including main mode, remained unchanged. The walking finding is therefore best read as a bounded, weighted survey estimate, not a census or a trend line.
