"So, areas where you have high influence of minority households, immigrant households, multi-family housing, and so it is – it's a particular challenge for our state," Lee-Sin says.
Florida has the fourth highest number of young children living in areas considered hard to count.
Lee-Sin says it's important to meet that challenge to ensure everyone is counted.
Florida gained two additional representatives after the 2010 census, and received more than $44 billion in federal dollars to support government programs.
Lee-Sin says the highest rate of under-count rests with the youngest Floridians – from birth to age four.
To avoid it requires significant outreach to families, and letting them know why it's important to fill the forms out accurately.
"Having an undercount and not taking stock of such a significant percentage of our population means that federal budgeting or appropriations – for things that support public education or highway or housing or road construction – may mean that we get a lesser amount than we should get," Lee-Sin explains
Lee-Sin is encouraging everyone to be on the lookout for the census forms and to start having conversations with friends and family about participating.
He adds there will be multiple opportunities to fill out forms including online, by standard mail, via phone and in some cases with in-person visit by a census representative.
