NOTES: Only trips in which the transportation mode, international/domestic status, and international destination could be determined are included. Trips to Europe or the Caribbean showing private vehicle or bus as the primary mode have been eliminated from this table and statistics have been calculated without those trips included.
On this table, differences are measured in columns instead of rows. The difference between shaded cells in the same column are not statistically significant.
Underlined estimates are based on a small sample size (<30) or a coefficient of variation greater than 30% and are not reliable.
