You can either use a Union Query to combine all the tables together, or you can use VBA to programattically search through each Table individually.
Example Union Query:
Code:
SELECT 'Table 1' AS [TableName], [Country], [Color], [Number], [Percentage], [Population] FROM [Table 1]
UNION SELECT 'Table 2' AS [TableName], [Country], [Color], [Number], [Percentage], [Population] FROM [Table 2]
UNION SELECT 'Table 3' AS [TableName], [Country], [Color], [Number], [Percentage], [Population] FROM [Table 3]
UNION SELECT 'Table 4' AS [TableName], [Country], [Color], [Number], [Percentage], [Population] FROM [Table 4]
WHERE [Country]='America'
