The country saw an average of more than 1.07 million entries and 1.03 million exits per day during this period, up 14.2 percent and 4.5 percent year-on-year, respectively. A total of 367,700 transportation carriers were inspected at the border checkpoints across the country, with the average daily number rising 12.95 percent year-on-year, according to the NIA.
