Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_name_86 ( south_asians_2001 INTEGER, province VARCHAR, south_asians_2011 VARCHAR )

### Question ###
How many South Asians on average were in Alberta in 2001 and in 2011 had 159,055?

### Accurate SQL ###

SELECT AVG(south_asians_2001) FROM table_name_86 WHERE province = "alberta" AND south_asians_2011 > 159 OFFSET 055
