Scotland recorded the highest footfall figures of all the regions and countries of the UK.
Year-on year, footfall in September was 0.9% down, as against same period a year ago, up on the 1.1% fall in August and in line with the three-month average of a 0.9% decline.
During the period, out-of-town reported the only rise, 0.5% higher than a year ago, while footfall on the high street was down 0.6% on the previous year.
Footfall in shopping centres was 2.6% down on the previous year for September, the deepest decline since October 2013.
All regions and countries with the exception of South East (1.4%), Northern Ireland (0.2%) and Scotland (2.0%) reported declining footfall.
SRC Policy & External Affairs head David Martin said: ""Following on from a strong set of results in August; shoppers continued to hit Scottish high streets and out of town shopping destinations in even greater numbers throughout September. Scotland recorded the highest footfall figures of any area of the UK with out of town retail the standout performer.
"Over the last 6 months footfall has increased in all but one of those months. This is an encouraging sign that the improvements we have see in both consumer confidence and the wider economy is feeding through to more consumers in store," Martin added.
Springboard Retail Insights director Diane Wehrle said: "In the face of a 0.9 per cent drop in footfall across the UK, a rise of 2 per cent in Scotland is positive."
