Last year, before starting the Census 2010, Perth Amboy mayor, Wilda Diaz visited Assumption Catholic School. She came to announce a challenge. The city was sponsoring a contest for all city elementary school students to predict what the city’s population would be when the census was completed.  After the results were counted, an official population count of 50,798 was determined.   Oleksandr Kalynyak, currently a sixth grade student, was the overall winner with a guess of 50,814. He was invited to City Hall to meet the mayor, who presented him with a proclamation to acknowledge his accomplishments. Congratulations Oleksandr!
